Sphinx is mainly a tool for formatting docs written independently from the source code, as I understand it.

For generating API docs from Python docstrings, the leading tools are pdoc and pydoctor. Here's pydoctor's generated API docs for Twisted and Bazaar.

Of course, if you just want to have a look at the docstrings while you're working on stuff, there's the "pydoc" command line tool and as well as the help() function available in the interactive interpreter.

If you wanted to make a global static variable:

var my_id = 123;

Replace the variable with the below:

Object.defineProperty(window, 'my_id', {
    get: function() {
            return 123;
        },
    configurable : false,
    enumerable : false
});

Using jQuery you can do:

$(window).width()
$(window).height()

The problem you have is that you're attempting to bind the "test" class to the event before there is anything with a "test" class in the DOM. Although it may seem like this is all dynamic, what is really happening is JQuery makes a pass over the DOM and wires up the click event when the ready() function fired, which happens before you created the "Click Me" in your button event.

By adding the "test" Click event to the "button" click handler it will wire it up after the correct element exists in the DOM.

<script type="text/javascript">
    $(document).ready(function(){                          
        $("button").click(function(){                                  
            $("h2").html("<p class='test'>click me</p>")                          
            $(".test").click(function(){                          
                alert()                          
            });       
        });                                     
    });
</script>

Using live() (as others have pointed out) is another way to do this but I felt it was also a good idea to point out the minor error in your JS code. What you wrote wasn't wrong, it just needed to be correctly scoped. Grasping how the DOM and JS works is one of the tricky things for many traditional developers to wrap their head around.

live() is a cleaner way to handle this and in most cases is the correct way to go. It essentially is watching the DOM and re-wiring things whenever the elements within it change.

Best easy way: Put the ABOUT Icon on your Office 2016 Application. Example Excel

1) Open Excel -> File -> Options -> Customize Ribbon

2) You 'll see 2 panes. Choose Commands From & Customize The Ribbon

3) From Choose Command, Select All Commands

4) From the resulting List Highlight About (Excel)

5) From the Customize The Ribbon Pain, Highlight Any Item (ex. View) where you want to put the About icon

6) Click New group at the bottom

7) Click the add button located between the two pane. DONE

Now when you click the View Tab in excel and click about you'll see 32 bit or 64 bit

I've written a few methods for convert by Gson library and java 1.8 .
thay are daynamic model for convert.

string to object

object to string

List to string

string to List

HashMap to String

String to JsonObj

//saeedmpt 
public static String convertMapToString(Map<String, String> data) {
    //convert Map  to String
    return new GsonBuilder().setPrettyPrinting().create().toJson(data);
}
public static <T> List<T> convertStringToList(String strListObj) {
    //convert string json to object List
    return new Gson().fromJson(strListObj, new TypeToken<List<Object>>() {
    }.getType());
}
public static <T> T convertStringToObj(String strObj, Class<T> classOfT) {
    //convert string json to object
    return new Gson().fromJson(strObj, (Type) classOfT);
}

public static JsonObject convertStringToJsonObj(String strObj) {
    //convert string json to object
    return new Gson().fromJson(strObj, JsonObject.class);
}

public static <T> String convertListObjToString(List<T> listObj) {
    //convert object list to string json for
    return new Gson().toJson(listObj, new TypeToken<List<T>>() {
    }.getType());
}

public static String convertObjToString(Object clsObj) {
    //convert object  to string json
    String jsonSender = new Gson().toJson(clsObj, new TypeToken<Object>() {
    }.getType());
    return jsonSender;
}

(This question came up high on a search engine result, but I ended up using a different approach. Adding an answer to this old question in case other people with similar questions read this)

You can solve this with Json.Net and make an extension method to handle the items you want to loop:

public static Tuple<string, int, int> ToTuple(this JToken token)
{
    var type = token["attributes"]["OBJECT_TYPE"].ToString();
    var x = token["position"]["x"].Value<int>();
    var y = token["position"]["y"].Value<int>();
    return new Tuple<string, int, int>(type, x, y);
}

And then access the data like this: (scenario: writing to console):

var tuples = JObject.Parse(myJsonString)["objects"].Select(item => item.ToTuple()).ToList();
tuples.ForEach(t => Console.WriteLine("{0}: ({1},{2})", t.Item1, t.Item2, t.Item3));

As the Python interpreter reads the definition of a function (or, I think, even a block of indented code), all variables that are assigned to inside the function are added to the locals for that function. If a local does not have a definition before an assignment, the Python interpreter does not know what to do, so it throws this error.

The solution here is to add

global feed

to your function (usually near the top) to indicate to the interpreter that the feed variable is not local to this function.

Assuming one has installed a JDK in /opt/java/jdk1.8.0_144 then:

1. Install the alternative for javac

   $ sudo update-alternatives --install /usr/bin/javac javac /opt/java/jdk1.8.0_144/bin/javac 1
   

2. Check / update the alternatives config:

   $ sudo update-alternatives --config javac
   

If there is only a single alternative for javac you will get a message saying so, otherwise select the option for the new JDK.

To check everything is setup correctly then:

$ which javac
/usr/bin/javac

$ ls -l /usr/bin/javac
lrwxrwxrwx 1 root root 23 Sep  4 17:10 /usr/bin/javac -> /etc/alternatives/javac

$ ls -l /etc/alternatives/javac
lrwxrwxrwx 1 root root 32 Sep  4 17:10 /etc/alternatives/javac -> /opt/java/jdk1.8.0_144/bin/javac

And finally

$ javac -version
javac 1.8.0_144

Repeat for java, keytool, jar, etc as needed.

For ng-click working properly you need define your controller after angularjs script binding and use it via $scope.

The repository is not down, it looks like they've changed how they host files (I guess they have restored some old code):

Now you have to add the /package-name/ before the -

Eg:

http://registry.npmjs.org/-/npm-1.1.48.tgz
http://registry.npmjs.org/npm/-/npm-1.1.48.tgz

There are 3 ways to solve it:

• Use a complete mirror:

• Use a public proxy:

  --registry http://165.225.128.50:8000

• Host a local proxy:

  https://github.com/hughsk/npm-quickfix

git clone https://github.com/hughsk/npm-quickfix.git
cd npm-quickfix
npm set registry http://localhost:8080/
node index.js

I'd personally go with number 3 and revert to npm set registry http://registry.npmjs.org/ as soon as this get resolved.

Stay tuned here for more info: https://github.com/isaacs/npm/issues/2694

Maybe like this?

I wrote a c++ program based on Win32 to write an assembly to the boot sector of a pen-drive. When the computer is booted from the pen-drive it executes the code successfully - have a look here C++ Program to write to the boot sector of a USB Pendrive

This program is a few lines that should be compiled on a compiler with windows compilation configured - such as a visual studio compiler - any available version.

In Win32:

#include<windows.h>
Sleep(milliseconds);

In Unix:

#include<unistd.h>
unsigned int microsecond = 1000000;
usleep(3 * microsecond);//sleeps for 3 second

sleep() only takes a number of seconds which is often too long.

I got it work by overriding annotation with XML file for Postgres. Annotation is kept for Oracle. In my opinion, in this case it would be best we override the mapping of this trouble-some enity with xml mapping. We can override single / multiple entities with xml mapping. So we would use annotation for our mainly-supported database, and a xml file for each other database.

Note: we just need to override one single class , so it is not a big deal. Read more from my example Example to override annotation with XML

A great way for cloning an array is with an array literal and the spread syntax. This is made possible by ES2015.

const objArray = [{name:'first'}, {name:'second'}, {name:'third'}, {name:'fourth'}];

const clonedArr = [...objArray];

console.log(clonedArr) // [Object, Object, Object, Object]

You can find this copy option in MDN's documentation: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Spread_operator#Copy_an_array

It is also an Airbnb's best practice. https://github.com/airbnb/javascript#es6-array-spreads

Note: The spread syntax in ES2015 goes one level deep while copying an array. Therefore, they are unsuitable for copying multidimensional arrays.

You'll get that error once your numbers are greater than sys.maxsize:

>>> p = [sys.maxsize]
>>> preds[0] = p
>>> p = [sys.maxsize+1]
>>> preds[0] = p
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
OverflowError: Python int too large to convert to C long

You can confirm this by checking:

>>> import sys
>>> sys.maxsize
2147483647

To take numbers with larger precision, don't pass an int type which uses a bounded C integer behind the scenes. Use the default float:

>>> preds = np.zeros((1, 3))

You could do it like this.

jsFiddle

JS

var select = document.getElementById('mySelect');
select.onchange = function () {
    select.className = this.options[this.selectedIndex].className;
}

CSS

.redText {
    background-color:#F00;
}
.greenText {
    background-color:#0F0;
}
.blueText {
    background-color:#00F;
}

You could use option { background-color: #FFF; } if you want the list to be white.

HTML

<select id="mySelect" class="greenText">
    <option class="greenText" value="apple" >Apple</option>
    <option class="redText"   value="banana" >Banana</option>
    <option class="blueText" value="grape" >Grape</option>
</select>

Since this is a select it doesn't really make sense to use .yellowText as none selected if that's what you were getting at as something must be selected.

The root of the problem is that you are unknowingly using the Frame class from the ttk package rather than from the tkinter package. The one from ttk does not support the background option.

This is the main reason why you shouldn't do global imports -- you can overwrite the definition of classes and commands.

I recommend doing imports like this:

import tkinter as tk
import ttk

Then you prefix the widgets with either tk or ttk :

f1 = tk.Frame(..., bg=..., fg=...)
f2 = ttk.Frame(..., style=...)

It then becomes instantly obvious which widget you are using, at the expense of just a tiny bit more typing. If you had done this, this error in your code would never have happened.

Whatever you want to use from another module, just put it in the export array. Like this-

 @NgModule({
  declarations: [TaskCardComponent],
  exports: [TaskCardComponent],
  imports: [MdCardModule]
})

I'm not sure if this will work exactly, but I thought of

var docwrite = function(doc) {               
    document.write(doc);          
};

This solved the problem with the error messages for me.

The naive way to do it is:

int myRand = rand() % 66; // for 0-65

This will likely be a very slightly non-uniform distribution (depending on your maximum value), but it's pretty close.

To explain why it's not quite uniform, consider this very simplified example:
Suppose RAND_MAX is 4 and you want a number from 0-2. The possible values you can get are shown in this table:

rand()   |  rand() % 3
---------+------------
0        |  0
1        |  1
2        |  2
3        |  0

See the problem? If your maximum value is not an even divisor of RAND_MAX, you'll be more likely to choose small values. However, since RAND_MAX is generally 32767, the bias is likely to be small enough to get away with for most purposes.

There are various ways to get around this problem; see here for an explanation of how Java's Random handles it.

In my experience this approach shouldn't be necessary. If you need the context for anything you can usually get it via a call to View.getContext() and using the Context obtained there you can call Context.getApplicationContext() to get the Application context. If you are trying to get the Application context this from an Activity you can always call Activity.getApplication() which should be able to be passed as the Context needed for a call to SQLiteOpenHelper().

Overall there doesn't seem to be a problem with your approach for this situation, but when dealing with Context just make sure you are not leaking memory anywhere as described on the official Google Android Developers blog.

You can use unequal comparison -ne instead of -eq:

wget -q --tries=10 --timeout=20 --spider http://google.com
if [[ $? -ne 0 ]]; then
    echo "Sorry you are Offline"
    exit 1
fi

when you create a job in nohup it will tell you the process ID !

nohup sh test.sh &

the output will show you the process ID like

25013

you can kill it then :

kill 25013

I recommend CsvHelper from Nuget.

PS: Regarding other more upvoted answers, I'm sorry but adding a reference to Microsoft.VisualBasic is:

• Ugly
• Not cross-platform, because it's not available in .NETCore/.NET5 (and Mono never had very good support of Visual Basic, so it may be buggy).

If you are just looking to intercept the traffic, you could use the fiddler core to create a proxy...

http://fiddler.wikidot.com/fiddlercore

run fiddler first with the UI to see what it does, it is a proxy that allows you to debug the http/https traffic. It is written in c# and has a core which you can build into your own applications.

Keep in mind FiddlerCore is not free for commercial applications.

Have you looked at Fiddler 2 from Microsoft?

http://www.fiddler2.com/fiddler2/

Allows you to generate most types of request for testing, including POST. It also supports capturing HTTP requests made by other applications and reusing those for testing.

I've gone through these posts and somehow ended up finding a simple answer, which I'm posting here for those how want short and sweet solutions:

1. Use console.log("Hello World") in your script.
2. Go to https://script.google.com/home/my and select your add-on.
3. Click on the ellipsis menu on Project Details, select Executions.

4. Click on the header of the latest execution and read the log.

Upload the file Microsoft.ReportViewer.WebForms.dll to your bin directory of your web applicaion.

You can find this dll file in the bin directory of your local web application.

Have you had a look at $routeProvider.when('/path',{ resolve:{...}? It can make the promise approach a bit cleaner:

Expose a promise in your service:

app.service('MyService', function($http) {
    var myData = null;

    var promise = $http.get('data.json').success(function (data) {
      myData = data;
    });

    return {
      promise:promise,
      setData: function (data) {
          myData = data;
      },
      doStuff: function () {
          return myData;//.getSomeData();
      }
    };
});

Add resolve to your route config:

app.config(function($routeProvider){
  $routeProvider
    .when('/',{controller:'MainCtrl',
    template:'<div>From MyService:<pre>{{data | json}}</pre></div>',
    resolve:{
      'MyServiceData':function(MyService){
        // MyServiceData will also be injectable in your controller, if you don't want this you could create a new promise with the $q service
        return MyService.promise;
      }
    }})
  }):

Your controller won't get instantiated before all dependencies are resolved:

app.controller('MainCtrl', function($scope,MyService) {
  console.log('Promise is now resolved: '+MyService.doStuff().data)
  $scope.data = MyService.doStuff();
});

I've made an example at plnkr: http://plnkr.co/edit/GKg21XH0RwCMEQGUdZKH?p=preview

As another variation on Totem's known type solution, you can use reflection to create a generic type resolver to avoid the need to use known type attributes.

This uses a technique similar to Juval Lowy's GenericResolver for WCF.

As long as your base class is abstract or an interface, the known types will be automatically determined rather than having to be decorated with known type attributes.

In my own case I opted to use a $type property to designate type in my json object rather than try to determine it from the properties, though you could borrow from other solutions here to use property based determination.

 public class JsonKnownTypeConverter : JsonConverter
{
    public IEnumerable<Type> KnownTypes { get; set; }

    public JsonKnownTypeConverter() : this(ReflectTypes())
    {

    }
    public JsonKnownTypeConverter(IEnumerable<Type> knownTypes)
    {
        KnownTypes = knownTypes;
    }

    protected object Create(Type objectType, JObject jObject)
    {
        if (jObject["$type"] != null)
        {
            string typeName = jObject["$type"].ToString();
            return Activator.CreateInstance(KnownTypes.First(x => typeName == x.Name));
        }
        else
        {
            return Activator.CreateInstance(objectType);
        }
        throw new InvalidOperationException("No supported type");
    }

    public override bool CanConvert(Type objectType)
    {
        if (KnownTypes == null)
            return false;

        return (objectType.IsInterface || objectType.IsAbstract) && KnownTypes.Any(objectType.IsAssignableFrom);
    }

    public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer)
    {
        // Load JObject from stream
        JObject jObject = JObject.Load(reader);

        // Create target object based on JObject
        var target = Create(objectType, jObject);
        // Populate the object properties
        serializer.Populate(jObject.CreateReader(), target);
        return target;
    }

    public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer)
    {
        throw new NotImplementedException();
    }

    //Static helpers
    static Assembly CallingAssembly = Assembly.GetCallingAssembly();

    static Type[] ReflectTypes()
    {
        List<Type> types = new List<Type>();
        var referencedAssemblies = Assembly.GetExecutingAssembly().GetReferencedAssemblies();
        foreach (var assemblyName in referencedAssemblies)
        {
            Assembly assembly = Assembly.Load(assemblyName);
            Type[] typesInReferencedAssembly = GetTypes(assembly);
            types.AddRange(typesInReferencedAssembly);
        }

        return types.ToArray();
    }

    static Type[] GetTypes(Assembly assembly, bool publicOnly = true)
    {
        Type[] allTypes = assembly.GetTypes();

        List<Type> types = new List<Type>();

        foreach (Type type in allTypes)
        {
            if (type.IsEnum == false &&
               type.IsInterface == false &&
               type.IsGenericTypeDefinition == false)
            {
                if (publicOnly == true && type.IsPublic == false)
                {
                    if (type.IsNested == false)
                    {
                        continue;
                    }
                    if (type.IsNestedPrivate == true)
                    {
                        continue;
                    }
                }
                types.Add(type);
            }
        }
        return types.ToArray();
    }

It can then be installed as a formatter

GlobalConfiguration.Configuration.Formatters.JsonFormatter.SerializerSettings.Converters.Add(new JsonKnownTypeConverter());

Swift 5 version of accepted answer:

let image = UIImage(named: "image_name")
let button = UIButton(type: UIButton.ButtonType.custom)
button.frame = CGRect(x: 100, y: 100, width: 200, height: 100)
button.setImage(image, for: .normal)
button.addTarget(self, action: #selector(function), for: .touchUpInside)

//button.backgroundColor = .lightGray
self.view.addSubview(button)

where of course

@objc func function() {...}

The image is aligned to center by default. You can change this by setting button's imageEdgeInsets, like this:

// In this case image is 40 wide and aligned to the left
button.imageEdgeInsets = UIEdgeInsets(top: 5, left: 5, bottom: 5, right: button.frame.width - 45)

There are three streaming protocols / technology in HTML5:

Live streaming, low latency - WebRTC - Websocket

VOD and Live streaming, high latency - HLS

1. WebRTC

In fact WebRTC is SRTP(secure RTP protocol). Thus we can say that video tag supports RTP(SRTP) indirectly via WebRTC.

Therefore to get RTP stream on your Chrome, Firefox or another HTML5 browser, you need a WebRTC server which will deliver the SRTP stream to browser.

2. Websocket

It is TCP based, but with lower latency than HLS. Again you need a Websocket server.

3. HLS

Most popular high-latency streaming protocol for VOD(pre-recorded video).

An easy option is to configure matplotlib to automatically adjust the plot size. It works perfectly for me and I'm not sure why it's not activated by default.

Method 1

Set this in your matplotlibrc file

figure.autolayout : True

See here for more information on customizing the matplotlibrc file: http://matplotlib.org/users/customizing.html

Method 2

Update the rcParams during runtime like this

from matplotlib import rcParams
rcParams.update({'figure.autolayout': True})

The advantage of using this approach is that your code will produce the same graphs on differently-configured machines.

Regex for minimum 8 char, one alpha, one numeric and one special char:

/^(?=.*[A-Za-z])(?=.*\d)(?=.*[!@#$%^&*])[A-Za-z\d!@#$%^&*]{8,}$/

I needed this same solution, but if you use the native ListObject.Add() method then you avoid the risk of clashing with any data immediately below the table. The below routine checks the last row of the table, and adds the data in there if it's blank; otherwise it adds a new row to the end of the table:

Sub AddDataRow(tableName As String, values() As Variant)
    Dim sheet As Worksheet
    Dim table As ListObject
    Dim col As Integer
    Dim lastRow As Range

    Set sheet = ActiveWorkbook.Worksheets("Sheet1")
    Set table = sheet.ListObjects.Item(tableName)

    'First check if the last row is empty; if not, add a row
    If table.ListRows.Count > 0 Then
        Set lastRow = table.ListRows(table.ListRows.Count).Range
        For col = 1 To lastRow.Columns.Count
            If Trim(CStr(lastRow.Cells(1, col).Value)) <> "" Then
                table.ListRows.Add
                Exit For
            End If
        Next col
    Else
        table.ListRows.Add
    End If

    'Iterate through the last row and populate it with the entries from values()
    Set lastRow = table.ListRows(table.ListRows.Count).Range
    For col = 1 To lastRow.Columns.Count
        If col <= UBound(values) + 1 Then lastRow.Cells(1, col) = values(col - 1)
    Next col
End Sub

To call the function, pass the name of the table and an array of values, one value per column. You can get / set the name of the table from the Design tab of the ribbon, in Excel 2013 at least:

Example code for a table with three columns:

Dim x(2)
x(0) = 1
x(1) = "apple"
x(2) = 2
AddDataRow "Table1", x

Similar to @Shravan, but without the use of numpy:

  height = 10
  width = 20
  df_0 = pd.DataFrame(0, index=range(height), columns=range(width))

Then you can do whatever you want with it:

post_instantiation_fcn = lambda x: str(x)
df_ready_for_whatever = df_0.applymap(post_instantiation_fcn)

I am not aware of any libraries to do this (but I am sure there are many that can) but if you can already create HTML from the crystal report why not use XSLT to clean up the markup?

Use the dec argument to set "," as the decimal point by adding:

 ce <- read.table("file.txt", header = TRUE, dec = ",")

I had a similar problem with dynamically adding datepicker classes. The solution I found was to comment out line 46 of datepicker.js

// this.element.on('click', $.proxy(this.show, this));

It depends on the Test Construct around the operator. Your options are double parentheses, double brackets, single brackets, or test.

If you use ((…)), you are testing arithmetic equality with == as in C:

$ (( 1==1 )); echo $?
0
$ (( 1==2 )); echo $?
1

(Note: 0 means true in the Unix sense and a failed test results in a non-zero number.)

Using -eq inside of double parentheses is a syntax error.

If you are using […] (or single brackets) or [[…]] (or double brackets), or test you can use one of -eq, -ne, -lt, -le, -gt, or -ge as an arithmetic comparison.

$ [ 1 -eq 1 ]; echo $?
0
$ [ 1 -eq 2 ]; echo $?
1
$ test 1 -eq 1; echo $?
0

The == inside of single or double brackets (or the test command) is one of the string comparison operators:

$ [[ "abc" == "abc" ]]; echo $?
0
$ [[ "abc" == "ABC" ]]; echo $?
1

As a string operator, = is equivalent to ==. Also, note the whitespace around = or ==: it’s required.

While you can do [[ 1 == 1 ]] or [[ $(( 1+1 )) == 2 ]] it is testing the string equality — not the arithmetic equality.

So -eq produces the result probably expected that the integer value of 1+1 is equal to 2 even though the right-hand side is a string and has a trailing space:

$ [[ $(( 1+1 )) -eq  "2 " ]]; echo $?
0

While a string comparison of the same picks up the trailing space and therefore the string comparison fails:

$ [[ $(( 1+1 )) == "2 " ]]; echo $?
1

And a mistaken string comparison can produce a completely wrong answer. 10 is lexicographically less than 2, so a string comparison returns true or 0. So many are bitten by this bug:

$ [[ 10 < 2 ]]; echo $?
0

The correct test for 10 being arithmetically less than 2 is this:

$ [[ 10 -lt 2 ]]; echo $?
1

In comments, there is a question about the technical reason why using the integer -eq on strings returns true for strings that are not the same:

$ [[ "yes" -eq "no" ]]; echo $?
0

The reason is that Bash is untyped. The -eq causes the strings to be interpreted as integers if possible including base conversion:

$ [[ "0x10" -eq 16 ]]; echo $?
0
$ [[ "010" -eq 8 ]]; echo $?
0
$ [[ "100" -eq 100 ]]; echo $?
0

And 0 if Bash thinks it is just a string:

$ [[ "yes" -eq 0 ]]; echo $?
0
$ [[ "yes" -eq 1 ]]; echo $?
1

So [[ "yes" -eq "no" ]] is equivalent to [[ 0 -eq 0 ]]

Last note: Many of the Bash specific extensions to the Test Constructs are not POSIX and therefore may fail in other shells. Other shells generally do not support [[...]] and ((...)) or ==.

If you don't feel like using Math.Abs * -1 you can you this simple if statement :P

if (x > 0) {
    x = -x;
}

Of course you could make this a function like this

function makeNegative(number) {
    if (number > 0) {
        number = -number;
    }
}

makeNegative(-3) => -3 makeNegative(5) => -5

Hope this helps! Math.abs will likely work for you but if it doesn't this little

$("input").is(":not(':checked')"))

This is jquery 1.3, mind the ' and " signs!

To resolve this issue:

1. The jstl jar should be in your classpath. If you are using maven, add a dependency to jstl in your pom.xml using the snippet provided here. If you are not using maven, download the jstl jar from here and deploy it into your WEB-INF/lib.

2. Make sure you have the following taglib directive at the top of your jsp:

A formal analysis has been done by Phil Rogaway in 2011, here. Section 1.6 gives a summary that I transcribe here, adding my own emphasis in bold (if you are impatient, then his recommendation is use CTR mode, but I suggest that you read my paragraphs about message integrity versus encryption below).

Note that most of these require the IV to be random, which means non-predictable and therefore should be generated with cryptographic security. However, some require only a "nonce", which does not demand that property but instead only requires that it is not re-used. Therefore designs that rely on a nonce are less error prone than designs that do not (and believe me, I have seen many cases where CBC is not implemented with proper IV selection). So you will see that I have added bold when Rogaway says something like "confidentiality is not achieved when the IV is a nonce", it means that if you choose your IV cryptographically secure (unpredictable), then no problem. But if you do not, then you are losing the good security properties. Never re-use an IV for any of these modes.

Also, it is important to understand the difference between message integrity and encryption. Encryption hides data, but an attacker might be able to modify the encrypted data, and the results can potentially be accepted by your software if you do not check message integrity. While the developer will say "but the modified data will come back as garbage after decryption", a good security engineer will find the probability that the garbage causes adverse behaviour in the software, and then he will turn that analysis into a real attack. I have seen many cases where encryption was used but message integrity was really needed more than the encryption. Understand what you need.

I should say that although GCM has both encryption and message integrity, it is a very fragile design: if you re-use an IV, you are screwed -- the attacker can recover your key. Other designs are less fragile, so I personally am afraid to recommend GCM based upon the amount of poor encryption code that I have seen in practice.

If you need both, message integrity and encryption, you can combine two algorithms: usually we see CBC with HMAC, but no reason to tie yourself to CBC. The important thing to know is encrypt first, then MAC the encrypted content, not the other way around. Also, the IV needs to be part of the MAC calculation.

I am not aware of IP issues.

Now to the good stuff from Professor Rogaway:

Block ciphers modes, encryption but not message integrity

ECB: A blockcipher, the mode enciphers messages that are a multiple of n bits by separately enciphering each n-bit piece. The security properties are weak, the method leaking equality of blocks across both block positions and time. Of considerable legacy value, and of value as a building block for other schemes, but the mode does not achieve any generally desirable security goal in its own right and must be used with considerable caution; ECB should not be regarded as a “general-purpose” confidentiality mode.

CBC: An IV-based encryption scheme, the mode is secure as a probabilistic encryption scheme, achieving indistinguishability from random bits, assuming a random IV. Confidentiality is not achieved if the IV is merely a nonce, nor if it is a nonce enciphered under the same key used by the scheme, as the standard incorrectly suggests to do. Ciphertexts are highly malleable. No chosen ciphertext attack (CCA) security. Confidentiality is forfeit in the presence of a correct-padding oracle for many padding methods. Encryption inefficient from being inherently serial. Widely used, the mode’s privacy-only security properties result in frequent misuse. Can be used as a building block for CBC-MAC algorithms. I can identify no important advantages over CTR mode.

CFB: An IV-based encryption scheme, the mode is secure as a probabilistic encryption scheme, achieving indistinguishability from random bits, assuming a random IV. Confidentiality is not achieved if the IV is predictable, nor if it is made by a nonce enciphered under the same key used by the scheme, as the standard incorrectly suggests to do. Ciphertexts are malleable. No CCA-security. Encryption inefficient from being inherently serial. Scheme depends on a parameter s, 1 = s = n, typically s = 1 or s = 8. Inefficient for needing one blockcipher call to process only s bits . The mode achieves an interesting “self-synchronization” property; insertion or deletion of any number of s-bit characters into the ciphertext only temporarily disrupts correct decryption.

OFB: An IV-based encryption scheme, the mode is secure as a probabilistic encryption scheme, achieving indistinguishability from random bits, assuming a random IV. Confidentiality is not achieved if the IV is a nonce, although a fixed sequence of IVs (eg, a counter) does work fine. Ciphertexts are highly malleable. No CCA security. Encryption and decryption inefficient from being inherently serial. Natively encrypts strings of any bit length (no padding needed). I can identify no important advantages over CTR mode.

CTR: An IV-based encryption scheme, the mode achieves indistinguishability from random bits assuming a nonce IV. As a secure nonce-based scheme, the mode can also be used as a probabilistic encryption scheme, with a random IV. Complete failure of privacy if a nonce gets reused on encryption or decryption. The parallelizability of the mode often makes it faster, in some settings much faster, than other confidentiality modes. An important building block for authenticated-encryption schemes. Overall, usually the best and most modern way to achieve privacy-only encryption.

XTS: An IV-based encryption scheme, the mode works by applying a tweakable blockcipher (secure as a strong-PRP) to each n-bit chunk. For messages with lengths not divisible by n, the last two blocks are treated specially. The only allowed use of the mode is for encrypting data on a block-structured storage device. The narrow width of the underlying PRP and the poor treatment of fractional final blocks are problems. More efficient but less desirable than a (wide-block) PRP-secure blockcipher would be.

MACs (message integrity but not encryption)

ALG1–6: A collection of MACs, all of them based on the CBC-MAC. Too many schemes. Some are provably secure as VIL PRFs, some as FIL PRFs, and some have no provable security. Some of the schemes admit damaging attacks. Some of the modes are dated. Key-separation is inadequately attended to for the modes that have it. Should not be adopted en masse, but selectively choosing the “best” schemes is possible. It would also be fine to adopt none of these modes, in favor of CMAC. Some of the ISO 9797-1 MACs are widely standardized and used, especially in banking. A revised version of the standard (ISO/IEC FDIS 9797-1:2010) will soon be released [93].

CMAC: A MAC based on the CBC-MAC, the mode is provably secure (up to the birthday bound) as a (VIL) PRF (assuming the underlying blockcipher is a good PRP). Essentially minimal overhead for a CBCMAC-based scheme. Inherently serial nature a problem in some application domains, and use with a 64-bit blockcipher would necessitate occasional re-keying. Cleaner than the ISO 9797-1 collection of MACs.

HMAC: A MAC based on a cryptographic hash function rather than a blockcipher (although most cryptographic hash functions are themselves based on blockciphers). Mechanism enjoys strong provable-security bounds, albeit not from preferred assumptions. Multiple closely-related variants in the literature complicate gaining an understanding of what is known. No damaging attacks have ever been suggested. Widely standardized and used.

GMAC: A nonce-based MAC that is a special case of GCM. Inherits many of the good and bad characteristics of GCM. But nonce-requirement is unnecessary for a MAC, and here it buys little benefit. Practical attacks if tags are truncated to = 64 bits and extent of decryption is not monitored and curtailed. Complete failure on nonce-reuse. Use is implicit anyway if GCM is adopted. Not recommended for separate standardization.

authenticated encryption (both encryption and message integrity)

CCM: A nonce-based AEAD scheme that combines CTR mode encryption and the raw CBC-MAC. Inherently serial, limiting speed in some contexts. Provably secure, with good bounds, assuming the underlying blockcipher is a good PRP. Ungainly construction that demonstrably does the job. Simpler to implement than GCM. Can be used as a nonce-based MAC. Widely standardized and used.

GCM: A nonce-based AEAD scheme that combines CTR mode encryption and a GF(2128)-based universal hash function. Good efficiency characteristics for some implementation environments. Good provably-secure results assuming minimal tag truncation. Attacks and poor provable-security bounds in the presence of substantial tag truncation. Can be used as a nonce-based MAC, which is then called GMAC. Questionable choice to allow nonces other than 96-bits. Recommend restricting nonces to 96-bits and tags to at least 96 bits. Widely standardized and used.

you could use setAttribute.

Example: For adding one class:

 document.getElementById('main').setAttribute("class","classOne"); 

For multiple classes:

 document.getElementById('main').setAttribute("class", "classOne classTwo"); 

System.String is a mutable object, meaning it cannot be modified after it’s been created. Please refer to Difference between string and StringBuilder in C#? for better understanding.

You can use the DataFrame method .apply() to operate on the values in Mycol:

>>> df = pd.DataFrame(['05SEP2014:00:00:00.000'],columns=['Mycol'])
>>> df
                    Mycol
0  05SEP2014:00:00:00.000
>>> import datetime as dt
>>> df['Mycol'] = df['Mycol'].apply(lambda x: 
                                    dt.datetime.strptime(x,'%d%b%Y:%H:%M:%S.%f'))
>>> df
       Mycol
0 2014-09-05

I store my data this way:

accountsTable ->
  key1 -> account1
  key2 -> account2

in order to get object data:

accountsDb = mDatabase.child("accountsTable");

accountsDb.child("some   key").addListenerForSingleValueEvent(new ValueEventListener() {
                @Override
                public void onDataChange(DataSnapshot snapshot) {

                    try{

                        Account account  = snapshot.getChildren().iterator().next()
                                  .getValue(Account.class);


                    } catch (Throwable e) {
                        MyLogger.error(this, "onCreate eror", e);
                    }
                }
                @Override public void onCancelled(DatabaseError error) { }
            });

I found the best solution here, the key of this issue is the addEntity method

public static void testSimpleSQL() {
    final Session session = sessionFactory.openSession();
    SQLQuery q = session.createSQLQuery("select * from ENTITY");
    q.addEntity(Entity.class);
    List<Entity> entities = q.list();
    for (Entity entity : entities) {
        System.out.println(entity);
    }
}

When I just run this as a page

<?php
echo '<script language="javascript">';
echo 'alert("message successfully sent")';
echo '</script>';
exit;

it works fine.

What version of PHP are you running?

Could you try echoing something else after: $testObject->split_for_sms($Chat);

Maybe it doesn't get to that part of the code? You could also try these with the other function calls to check where your program stops/is getting to.

Hope you get a bit further with this.

Use ROW_NUMBER() instead. ROWNUM is a pseudocolumn and ROW_NUMBER() is a function. You can read about difference between them and see the difference in output of below queries:

SELECT * FROM (SELECT rownum, deptno, ename
           FROM scott.emp
        ORDER BY deptno
       )
 WHERE rownum <= 3
 /

ROWNUM    DEPTNO    ENAME
---------------------------
 7        10    CLARK
 14       10    MILLER
 9        10    KING


 SELECT * FROM 
 (
  SELECT deptno, ename
       , ROW_NUMBER() OVER (ORDER BY deptno) rno
  FROM scott.emp
 ORDER BY deptno
 )
WHERE rno <= 3
/

DEPTNO    ENAME    RNO
-------------------------
10    CLARK        1
10    MILLER       2
10    KING         3

mysql.exe is included in mysql package. You don't have to install anything additionally.

You may consider declaring the variables with moudule level scope. Module-level variable is available to all of the procedures in that module, but it is not available to procedures in other modules

Please copy the below code into any module, save the workbook and then run the code.

Here is what code does

• The sample subroutine sets the folder path & later the file path. Kindly set them accordingly before you run the code.

• I have added a function IsWorkBookOpen to check if workbook is already then set the workbook variable the workbook name else open the workbook which will be assigned to workbook variable accordingly.

Dim wbA As Workbook
Dim wbB As Workbook

Sub MySubRoutine()
    Dim folderPath As String, fileNm1 As String, fileNm2 As String, filePath1 As String, filePath2 As String

    folderPath = ThisWorkbook.Path & "\"
    fileNm1 = "file1.xlsx"
    fileNm2 = "file2.xlsx"

    filePath1 = folderPath & fileNm1
    filePath2 = folderPath & fileNm2

    If IsWorkBookOpen(filePath1) Then
        Set wbA = Workbooks(fileNm1)
    Else
        Set wbA = Workbooks.Open(filePath1)
    End If


    If IsWorkBookOpen(filePath2) Then
        Set wbB = Workbooks.Open(fileNm2)
    Else
        Set wbB = Workbooks.Open(filePath2)
    End If


    ' your code here
End Sub

Function IsWorkBookOpen(FileName As String)
    Dim ff As Long, ErrNo As Long

    On Error Resume Next
    ff = FreeFile()
    Open FileName For Input Lock Read As #ff
    Close ff
    ErrNo = Err
    On Error GoTo 0

    Select Case ErrNo
    Case 0: IsWorkBookOpen = False
    Case 70: IsWorkBookOpen = True
    Case Else: Error ErrNo
    End Select
End Function

Using Prompt to select the file use below code.

Dim wbA As Workbook
Dim wbB As Workbook

Sub MySubRoutine()
    Dim folderPath As String, fileNm1 As String, fileNm2 As String, filePath1 As String, filePath2 As String

    Dim filePath As String
    cmdBrowse_Click filePath, 1

    filePath1 = filePath

    'reset the variable
    filePath = vbNullString

    cmdBrowse_Click filePath, 2
    filePath2 = filePath

   fileNm1 = GetFileName(filePath1, "\")
   fileNm2 = GetFileName(filePath2, "\")

    If IsWorkBookOpen(filePath1) Then
        Set wbA = Workbooks(fileNm1)
    Else
        Set wbA = Workbooks.Open(filePath1)
    End If


    If IsWorkBookOpen(filePath2) Then
        Set wbB = Workbooks.Open(fileNm2)
    Else
        Set wbB = Workbooks.Open(filePath2)
    End If


    ' your code here
End Sub

    Dim ff As Long, ErrNo As Long

    On Error Resume Next
    ff = FreeFile()
    Open FileName For Input Lock Read As #ff
    Close ff
    ErrNo = Err
    On Error GoTo 0

    Select Case ErrNo
    Case 0: IsWorkBookOpen = False
    Case 70: IsWorkBookOpen = True
    Case Else: Error ErrNo
    End Select
End Function

Private Sub cmdBrowse_Click(ByRef filePath As String, num As Integer)

    Dim fd As FileDialog
    Set fd = Application.FileDialog(msoFileDialogFilePicker)

    fd.InitialView = msoFileDialogViewSmallIcons

    Dim FileChosen As Integer

    FileChosen = fd.Show

    fd.Filters.Clear
    fd.Filters.Add "Excel macros", "*.xlsx"


    fd.FilterIndex = 1



    If FileChosen <> -1 Then
        MsgBox "You chose cancel"
        filePath = ""
    Else
        filePath = fd.SelectedItems(1)

Function GetFileName(fullName As String, pathSeparator As String) As String

    Dim i As Integer
    Dim iFNLenght As Integer
    iFNLenght = Len(fullName)

    For i = iFNLenght To 1 Step -1
        If Mid(fullName, i, 1) = pathSeparator Then Exit For
    Next

    GetFileName = Right(fullName, iFNLenght - i)

End Function

10 is the initial capacity of the AL, not the size (which is 0). You should mention the initial capacity to some high value when you are going to have a lots of elements, because it avoids the overhead of expanding the capacity as you keep adding elements.

Unicode codepoints U+D800 to U+DFFF must be avoided: they are invalid in Unicode because they are reserved for UTF-16 surrogate pairs. Some JSON encoders/decoders will replace them with U+FFFD. See for example how the Go language and its JSON library deals with them.

So avoid "\uD800" to "\uDFFF" alone (not in surrogate pairs).

Use this snippet:

@echo off
echo something
echo.
echo press enter to exit
pause >nul
exit

Note - if you want to pass a data attribute to a React Component, you need to handle them a little differently than other props.

2 options

Don't use camel case

<Option data-img-src='value' ... />

And then in the component, because of the dashes, you need to refer to the prop in quotes.

// @flow
class Option extends React.Component {

  props: {
    'data-img-src': string
  }

And when you refer to it later, you don't use the dot syntax

  render () {
    return (
      <option data-img-src={this.props['data-img-src']} >...</option>
    )
  }
}

Or use camel case

<Option dataImgSrc='value' ... />

And then in the component, you need to convert.

// @flow
class Option extends React.Component {

  props: {
    dataImgSrc: string
  }

And when you refer to it later, you don't use the dot syntax

  render () {
    return (
      <option data-img-src={this.props.dataImgSrc} >...</option>
    )
  }
}

Mainly just realize data- attributes and aria- attributes are treated specially. You are allowed to use hyphens in the attribute name in those two cases.

Just consider how the SWITCH might work,

• in case of primitives we know it can fail with NPE for auto-boxing
• but for String or enum, it might be invoking equals method, which obviously needs a LHS value on which equals is being invoked. So, given no method can be invoked on a null, switch cant handle null.

You've probably got Option Strict turned on (which is a good thing), and the compiler is telling you that you can't add a string and an int. Try this:

t = s1 & i.ToString()

A more verbose way would be to use this function.

int length(int n)
{
    bool stop;
    int nDigits = 0;
    int dividend = 1;
    do
    {
        stop = false;
        if (n > dividend)
        {
            nDigits = nDigits + 1;
            dividend = dividend * 10;
        }
        else {
            stop = true;
        }


    }
    while (stop == false);
    return nDigits;
}

This worked for me On Windows 10,

xcopy /s {source drive..i.e. C:} {destination drive..i.e. D:} This will copy all the files and folders plus the folder contents.

If you want to display date time on view without model, just write this:

Date : @DateTime.Now

The output will be:

Date : 16-Aug-17 2:32:10 PM

If you read JavaScript The Good Parts, you'll see that Crockford's replacement for i++ in a for loop is i+=1 (not i=i+1). That's pretty clean and readable, and is less likely to morph into something "tricky."

Crockford made disallowing autoincrement and autodecrement an option in jsLint. You choose whether to follow the advice or not.

My own personal rule is to not do anything combined with autoincrement or autodecrement.

I've learned from years of experience in C that I don't get buffer overruns (or array index out of bounds) if I keep use of it simple. But I've discovered that I do get buffer overruns if I fall into the "excessively tricky" practice of doing other things in the same statement.

So, for my own rules, the use of i++ as the increment in a for loop is fine.

As far as I can see in the manual, it is not possible to call functions inside HEREDOC strings. A cumbersome way would be to prepare the words beforehand:

<?php

    $world = _("World");

    $str = <<<EOF
    <p>Hello</p>
    <p>$world</p>
EOF;
    echo $str;
?>

a workaround idea that comes to mind is building a class with a magic getter method.

You would declare a class like this:

class Translator
{
 public function __get($name) {
  return _($name); // Does the gettext lookup
  }
 }

Initialize an object of the class at some point:

  $translate = new Translator();

You can then use the following syntax to do a gettext lookup inside a HEREDOC block:

    $str = <<<EOF
    <p>Hello</p>
    <p>{$translate->World}</p>
EOF;
    echo $str;
?>

$translate->World will automatically be translated to the gettext lookup thanks to the magic getter method.

To use this method for words with spaces or special characters (e.g. a gettext entry named Hello World!!!!!!, you will have to use the following notation:

 $translate->{"Hello World!!!!!!"}

This is all untested but should work.

Update: As @mario found out, it is possible to call functions from HEREDOC strings after all. I think using getters like this is a sleek solution, but using a direct function call may be easier. See the comments on how to do this.

Use cURL:

*/5 * * * * curl http://example.com/check/

Neat and clean:

import java.io.File;

public class RevCreateDirectory {

    public void revCreateDirectory() {
        //To create single directory/folder
        File file = new File("D:\\Directory1");
        if (!file.exists()) {
            if (file.mkdir()) {
                System.out.println("Directory is created!");
            } else {
                System.out.println("Failed to create directory!");
            }
        }
        //To create multiple directories/folders
        File files = new File("D:\\Directory2\\Sub2\\Sub-Sub2");
        if (!files.exists()) {
            if (files.mkdirs()) {
                System.out.println("Multiple directories are created!");
            } else {
                System.out.println("Failed to create multiple directories!");
            }
        }

    }
}

Not very "elegant" and kinda a waste, but if you really care what the code looks like you could make your own fancy flag and then do a str_replace.

Example:<br />
$myoutput =  "After this sentence there is a line break.<b>.|..</b> Here is a new line.";<br />
$myoutput =  str_replace(".|..","&lt;br />",$myoutput);<br />

or

how about:<br />
$myoutput =  "After this sentence there is a line break.<b>E(*)3</b> Here is a new line.";<br />
$myoutput =  str_replace("E(*)3","&lt;br />",$myoutput);<br />

I call the first method "middle finger style" and the second "goatse style".

A two value assignment can be used for this purpose. Please check my sample program below

package main

import (
    "fmt"
)

func main() {
    //creating a map with 3 key-value pairs
    sampleMap := map[string]int{"key1": 100, "key2": 500, "key3": 999}
    //A two value assignment can be used to check existence of a key.
    value, isKeyPresent := sampleMap["key2"]
    //isKeyPresent will be true if key present in sampleMap
    if isKeyPresent {
        //key exist
        fmt.Println("key present, value =  ", value)
    } else {
        //key does not exist
        fmt.Println("key does not exist")
    }
}

Same problem occurd with me, with AWS RDS MySQL. Just now, answered similar question here. Looked various sources, but as of this thread, almost all lack of answer. While this thread helped me, tweak in mind to update hostnames at server. Access your SSH and follow the steps:

cd /etc/
sudo nano hosts

Now, Appending here your hostnames: For example:

127.0.0.1 localhost
127.0.0.1 subdomain.domain.com [if cname redirected to endpoints]
127.0.0.1 xxxxxxxx.xxxx.xxxxx.rds.amazonaws.com [Endpoints]

and now, configuring config/database.php as follows:

$active_group = 'default';
$query_builder = TRUE;

$db['default'] = array(
    'dsn'   => '',
    'hostname' => '35.150.12.345',
    'username' => 'user-name-here',
    'password' => 'password-here',
    'database' => 'database-name-here',
    'dbdriver' => 'mysqli',
    'dbprefix' => '',
    'pconnect' => FALSE,
    'db_debug' => TRUE,
    'cache_on' => FALSE,
    'cachedir' => '',
    'char_set' => 'utf8',
    'dbcollat' => 'utf8_general_ci',
    'swap_pre' => '',
    'encrypt' => FALSE,
    'compress' => FALSE,
    'stricton' => FALSE,
    'failover' => array(),
    'save_queries' => TRUE
);

where 35.150.12.345 is your IPv4 Public IP, located at ec2-dashboard > Network Interfaces > Description : RDSNetworkInterface >> IPv4 Public IP('35.150.12.345') there.

Note: Please note that only IPV4 will work at 'hostname' option. hostname, cname, domains will output database connection error.

Try this:

panel1.BackColor = Color.FromArgb(100, 88, 44, 55);

change alpha(A) to get desired opacity.

Are you using Windows Forms? If you've added the image using the Properties/Resources UI, you get access to the image from generated code, so you can simply do this:

var bmp = new Bitmap(WindowsFormsApplication1.Properties.Resources.myimage);

Edit:

Are you trying to do sth like this? See: http://twitter.github.com/bootstrap/javascript.html#tabs

See the working example: http://jsfiddle.net/U6aKT/

<a href="#id">go to id</a>
<div style="margin-top:2000px;"></div>
<a id="id">id</a>

Your code looks syntactically correct, but I think your property doesn't exist to create the URL.

I just tested it, and it works fine for me.

Try using category.idCategory instead of category.id, for example…

  <tr th:each="category : ${categories}">
    <td th:text="${category.idCategory}"></td>
    <td th:text="${category.name}"></td>
    <td>
      <a th:href="@{'/category/edit/' + ${category.idCategory}}">view</a>
    </td>
  </tr>

I know this question is old, but this is a much easier alternative:

header_remove();

But be careful! It will erase ALL headers, including Cookies, Session, etc., as explained in the docs.

Try this:

@echo off &setlocal
setlocal enabledelayedexpansion

set "search=%1"
set "replace=%2"
set "textfile=Input.txt"
set "newfile=Output.txt"
(for /f "delims=" %%i in (%textfile%) do (
    set "line=%%i"
    set "line=!line:%search%=%replace%!"
    echo(!line!
))>"%newfile%"
del %textfile%
rename %newfile%  %textfile%
endlocal

Have you looked at vincent? Vincent takes Python data objects and converts them to Vega visualization grammar. Vega is a higher-level visualization tool built on top of D3. As compared to D3py, the vincent repo has been updated more recently. Though the examples are all static D3.

more info:

• https://github.com/wrobstory/vincent

• https://pypi.python.org/pypi/vincent/0.1.6

The graphs can be viewed in Ipython, just add this code

vincent.core.initialize_notebook()

Or output to JSON where you can view the JSON output graph in the Vega online editor (http://trifacta.github.io/vega/editor/) or view them on your Python server locally. More info on viewing can be found in the pypi link above.

Not sure when, but the Pandas package should have D3 integration at some point. http://pandas.pydata.org/developers.html

Bokeh is a Python visualization library that supports interactive visualization. Its primary output backend is HTML5 Canvas and uses client/server model.

examples: http://continuumio.github.io/bokehjs/

you can use paste0 or cat method to combine string with variable values in R

For Example:

paste0("Value of A : ", a)

cat("Value of A : ", a)

here is a great article of how to vetical align.. I like the float way.

http://www.vanseodesign.com/css/vertical-centering/

The HTML:

<div id="main">
    <div id="floater"></div>
    <div id="inner">Content here</div>
</div>

And the corresponding style:

#main {
   height: 250px;
}

#floater {
   float: left;
   height: 50%;
   width: 100%;
   margin-bottom: -50px;
}

#inner {
   clear: both;
   height: 100px;
}

Something like this?

DEMO

And the code I used:

.box{
    position: relative;
    overflow: hidden;
}

.box:hover .hidden{

    left: 0px;
}

.box .hidden {    
    background: yellow;
    height: 300px;    
    position: absolute; 
    top: 0;
    left: -500px;    
    width: 500px;
    opacity: 1;    
    -webkit-transition: all 0.7s ease-out;
       -moz-transition: all 0.7s ease-out;
        -ms-transition: all 0.7s ease-out;
         -o-transition: all 0.7s ease-out;
            transition: all 0.7s ease-out;
}

I may also add that it's possible to move an elment using transform: translate(); , which in this case could work something like this - DEMO nr2

If you came here from google because tab isnt indenting, this can also be because "Tab Moves Focus" is on. It is at the bottom right, and if you have a large enough monitor you may miss it despite it being highlighted.

Click the Green area or Ctrl + M to make it stop. I'm not sure it can be disabled entirely, then again I dont know why a code editor would want to mess with something like indenting.

There really isn't a need to create a custom click event as suggested in the bountied answer or to show the url as suggested in the accepted answer.

window.open(url)¹ does open web pages automatically without user interaction, provided pop- up blockers are disabled(as is the case with Stephen's answer)

openUrl.html

<!DOCTYPE html>
<html>
  <head>
   <base target="_blank">
    <script>
     var url1 ='https://stackoverflow.com/a/54675103';
     var winRef = window.open(url1);
     winRef ? google.script.host.close() : window.alert('Allow popup to redirect you to '+url1) ;
     window.onload=function(){document.getElementById('url').href = url1;}
    </script>
  </head>
  <body>
    Kindly allow pop ups</br>
    Or <a id='url'>Click here </a>to continue!!!
  </body>
</html>

code.gs:

function modalUrl(){
  SpreadsheetApp.getUi()
   .showModalDialog(
     HtmlService.createHtmlOutputFromFile('openUrl').setHeight(50),
     'Opening StackOverflow'
   )
}    

Take a look at the Cursor.Position Property. It should get you started.

private void MoveCursor()
{
   // Set the Current cursor, move the cursor's Position,
   // and set its clipping rectangle to the form. 

   this.Cursor = new Cursor(Cursor.Current.Handle);
   Cursor.Position = new Point(Cursor.Position.X - 50, Cursor.Position.Y - 50);
   Cursor.Clip = new Rectangle(this.Location, this.Size);
}

I figured the issue. Its because Charles 3.7 has some bugs for Android devices. I updated to Charles 3.8 Beta version and seems to working fine for me.

In basic terms synchronous requests wait for the response to be received from the request before it allows any code processing to continue. At first this may seem like a good thing to do, but it absolutely is not.

As mentioned, while the request is in process the browser will halt execution of all script and also rendering of the UI as the JS engine of the majority of browsers is (effectively) single-threaded. This means that to your users the browser will appear unresponsive and they may even see OS-level warnings that the program is not responding and to ask them if its process should be ended. It's for this reason that synchronous JS has been deprecated and you see warnings about its use in the devtools console.

The alternative of asynchronous requests is by far the better practice and should always be used where possible. This means that you need to know how to use callbacks and/or promises in order to handle the responses to your async requests when they complete, and also how to structure your JS to work with this pattern. There are many resources already available covering this, this, for example, so I won't go into it here.

There are very few occasions where a synchronous request is necessary. In fact the only one I can think of is when making a request within the beforeunload event handler, and even then it's not guaranteed to work.

In summary. you should look to learn and employ the async pattern in all requests. Synchronous requests are now an anti-pattern which cause more issues than they generally solve.

Instead of appending element you can just do.

 document.getElementById("p").textContent += " this has just been added";

document.getElementById("p").textContent += " this has just been added";

<p id ="p">This is some text</p>

what happened to me is that I have multiple projects in my solution. I meant to debug project 1, however, the project 2 was set as the default starting project. I fixed this by, right click on the project and select "Set as startup project", then running debugging is fine.

You can use postForObject with an HttpEntity. It would look like this:

HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_JSON);
headers.set("Authorization", "Bearer "+accessToken);

HttpEntity<String> entity = new HttpEntity<String>(requestJson,headers);
String result = restTemplate.postForObject(url, entity, String.class);

In a GET request, you'd usually not send a body (it's allowed, but it doesn't serve any purpose). The way to add headers without wiring the RestTemplate differently is to use the exchange or execute methods directly. The get shorthands don't support header modification.

The asymmetry is a bit weird on a first glance, perhaps this is going to be fixed in future versions of Spring.

I've noticed that if you set the theme in the AndroidManifest, it seems to get rid of that short time where you can see the action bar. So, try adding this to your manifest:

<android:theme="@android:style/Theme.NoTitleBar">

Just add it to your application tag to apply it app-wide.

This is how I implemented Spring MVC Multipart Request with JSON Data.

Multipart Request with JSON Data (also called Mixed Multipart):

Based on RESTful service in Spring 4.0.2 Release, HTTP request with the first part as XML or JSON formatted data and the second part as a file can be achieved with @RequestPart. Below is the sample implementation.

Java Snippet:

Rest service in Controller will have mixed @RequestPart and MultipartFile to serve such Multipart + JSON request.

@RequestMapping(value = "/executesampleservice", method = RequestMethod.POST,
    consumes = {"multipart/form-data"})
@ResponseBody
public boolean executeSampleService(
        @RequestPart("properties") @Valid ConnectionProperties properties,
        @RequestPart("file") @Valid @NotNull @NotBlank MultipartFile file) {
    return projectService.executeSampleService(properties, file);
}

Front End (JavaScript) Snippet:

1. Create a FormData object.

2. Append the file to the FormData object using one of the below steps.

   1. If the file has been uploaded using an input element of type "file", then append it to the FormData object. formData.append("file", document.forms[formName].file.files[0]);
   2. Directly append the file to the FormData object. formData.append("file", myFile, "myfile.txt"); OR formData.append("file", myBob, "myfile.txt");

3. Create a blob with the stringified JSON data and append it to the FormData object. This causes the Content-type of the second part in the multipart request to be "application/json" instead of the file type.

4. Send the request to the server.

5. Request Details:
   Content-Type: undefined. This causes the browser to set the Content-Type to multipart/form-data and fill the boundary correctly. Manually setting Content-Type to multipart/form-data will fail to fill in the boundary parameter of the request.

Javascript Code:

formData = new FormData();

formData.append("file", document.forms[formName].file.files[0]);
formData.append('properties', new Blob([JSON.stringify({
                "name": "root",
                "password": "root"                    
            })], {
                type: "application/json"
            }));

Request Details:

method: "POST",
headers: {
         "Content-Type": undefined
  },
data: formData

Request Payload:

Accept:application/json, text/plain, */*
Content-Type:multipart/form-data; boundary=----WebKitFormBoundaryEBoJzS3HQ4PgE1QB

------WebKitFormBoundaryvijcWI2ZrZQ8xEBN
Content-Disposition: form-data; name="file"; filename="myfile.txt"
Content-Type: application/txt

Content-Type: application/json

None of these attributes are reliable because per the servlet spec (2.4, 2.5 and 3.0), these attributes are overridden if you include/forward a second time (or if someone calls getNamedDispatcher). I think the only reliable way to get the original request URI/query string is to stick a filter at the beginning of your filter chain in web.xml that sets your own custom request attributes based on request.getRequestURI()/getQueryString() before any forwards/includes take place.

http://www.caucho.com/resin-3.0/webapp/faq.xtp contains an excellent summary of how this works (minus the technical note that a second forward/include messes up your ability to use these attributes).

Use "-S" as an option. It displays the assembly output in the terminal.

Since version 0.18.1 the .loc method accepts a callable for selection. Together with lambda functions you can create very flexible chainable filters:

import numpy as np
import pandas as pd

df = pd.DataFrame(np.random.randint(0,100,size=(100, 4)), columns=list('ABCD'))
df.loc[lambda df: df.A == 80]  # equivalent to df[df.A == 80] but chainable

df.sort_values('A').loc[lambda df: df.A > 80].loc[lambda df: df.B > df.A]

If all you're doing is filtering, you can also omit the .loc.

you have to create an entry inside res/menu,override onCreateOptionsMenu and inflate it

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.yourentry, menu);
    return true;
}

an entry for the menu could be:

<menu xmlns:android="http://schemas.android.com/apk/res/android" >
    <item
        android:id="@+id/action_cart"
        android:icon="@drawable/cart"
        android:orderInCategory="100"
        android:showAsAction="always"/> 
</menu>

You can use this syntax:

#!/bin/bash

echo " Write in your age: "
read age

if [[ "$age" -le 7 || "$age" -ge 65 ]] ; then
    echo " You can walk in for free "
elif [[ "$age" -gt 7 && "$age" -lt 65 ]] ; then
    echo " You have to pay for ticket "
fi

<input onkeyup="this.setAttribute('value', this.value);" />

and

input[value=""]

will work :-)

edit: http://jsfiddle.net/XwZR2/

Just to have a simple and complete example for Python 3, which most people seem to be using now.

class MySuper(object):
    def __init__(self,a):
        self.a = a

class MySub(MySuper):
    def __init__(self,a,b):
        self.b = b
        super().__init__(a)

my_sub = MySub(42,'chickenman')
print(my_sub.a)
print(my_sub.b)

gives

42
chickenman

The Maximally Standards Compliant way to do it is to create a text node containing the text you want and append it to the span (removing any currently extant text nodes).

The way I would actually do it is to use jQuery's .text().

Definitely the easiest way to do that is using Gson's default parsing function fromJson().

There is an implementation of this function suitable for when you need to deserialize into any ParameterizedType (e.g., any List), which is fromJson(JsonElement json, Type typeOfT).

In your case, you just need to get the Type of a List<String> and then parse the JSON array into that Type, like this:

import java.lang.reflect.Type;
import com.google.gson.reflect.TypeToken;

JsonElement yourJson = mapping.get("servers");
Type listType = new TypeToken<List<String>>() {}.getType();

List<String> yourList = new Gson().fromJson(yourJson, listType);

In your case yourJson is a JsonElement, but it could also be a String, any Reader or a JsonReader.

You may want to take a look at Gson API documentation.

Most of the jQuery Ajax methods return an XMLHttpRequest (or the equivalent) object, so you can just use abort().

See the documentation:

• abort Method (MSDN). Cancels the current HTTP request.
• abort() (MDN). If the request has been sent already, this method will abort the request.

var xhr = $.ajax({
    type: "POST",
    url: "some.php",
    data: "name=John&location=Boston",
    success: function(msg){
       alert( "Data Saved: " + msg );
    }
});

//kill the request
xhr.abort()

UPDATE: As of jQuery 1.5 the returned object is a wrapper for the native XMLHttpRequest object called jqXHR. This object appears to expose all of the native properties and methods so the above example still works. See The jqXHR Object (jQuery API documentation).

UPDATE 2: As of jQuery 3, the ajax method now returns a promise with extra methods (like abort), so the above code still works, though the object being returned is not an xhr any more. See the 3.0 blog here.

UPDATE 3: xhr.abort() still works on jQuery 3.x. Don't assume the update 2 is correct. More info on jQuery Github repository.

The two above it is not run.

The table edit button:

<a data-toggle="modal" type="edit" id="{{$b->id}}" data-id="{{$b->id}}"  data-target="#form_edit_masterbank" data-bank_nama="{{ $b->bank_nama }}" data-bank_accnama="{{ $b->bank_accnama }}" data-bank_accnum="{{ $b->bank_accnum }}" data-active="{{ $b->active }}" data-logobank="{{asset('components/images/user/masterbank/')}}/{{$b->images}}" href="#"  class="edit edit-masterbank"   ><i class="fa fa-edit" ></i></a>                                               

and then in JavaScript:

$('.imagepreview555').attr('src', logobank);

and then in HTML:

<img src="" class="imagepreview555"  style="width: 100%;" />

Not it runs.

If you want to print the columns after the 3rd for example in the same line, you can use:

awk '{for(i=3; i<=NF; ++i) printf "%s ", $i; print ""}'

For example:

Mar 09:39 20180301_123131.jpg
Mar 13:28 20180301_124304.jpg
Mar 13:35 20180301_124358.jpg

Feb 12:49 Docker.dmg
Feb 09:04 Grammarly.dmg
Feb 09:20 Payslip 10459 %2828-02-2018%29.pdf

It will print:

20180301_123131.jpg
20180301_124304.jpg
20180301_124358.jpg
Cisco_WebEx_Add-On.dmg

Grammarly.dmg
Payslip 10459 %2828-02-2018%29.pdf

As we can see, the payslip even with space, shows in the correct line.

Maybe my answer is too late but this can help others.

You can enclose it with another select statement and use where clause to it.

SELECT * FROM (Select col1, col2,...) as t WHERE t.calcAlias > 0

calcAlias is the alias column that was calculated.

Welcome to the wonderful world of portability... or rather the lack of it. Before we start analyzing these two options in detail and take a deeper look how different operating systems handle them, it should be noted that the BSD socket implementation is the mother of all socket implementations. Basically all other systems copied the BSD socket implementation at some point in time (or at least its interfaces) and then started evolving it on their own. Of course the BSD socket implementation was evolved as well at the same time and thus systems that copied it later got features that were lacking in systems that copied it earlier. Understanding the BSD socket implementation is the key to understanding all other socket implementations, so you should read about it even if you don't care to ever write code for a BSD system.

There are a couple of basics you should know before we look at these two options. A TCP/UDP connection is identified by a tuple of five values:

{<protocol>, <src addr>, <src port>, <dest addr>, <dest port>}

Any unique combination of these values identifies a connection. As a result, no two connections can have the same five values, otherwise the system would not be able to distinguish these connections any longer.

The protocol of a socket is set when a socket is created with the socket() function. The source address and port are set with the bind() function. The destination address and port are set with the connect() function. Since UDP is a connectionless protocol, UDP sockets can be used without connecting them. Yet it is allowed to connect them and in some cases very advantageous for your code and general application design. In connectionless mode, UDP sockets that were not explicitly bound when data is sent over them for the first time are usually automatically bound by the system, as an unbound UDP socket cannot receive any (reply) data. Same is true for an unbound TCP socket, it is automatically bound before it will be connected.

If you explicitly bind a socket, it is possible to bind it to port 0, which means "any port". Since a socket cannot really be bound to all existing ports, the system will have to choose a specific port itself in that case (usually from a predefined, OS specific range of source ports). A similar wildcard exists for the source address, which can be "any address" (0.0.0.0 in case of IPv4 and :: in case of IPv6). Unlike in case of ports, a socket can really be bound to "any address" which means "all source IP addresses of all local interfaces". If the socket is connected later on, the system has to choose a specific source IP address, since a socket cannot be connected and at the same time be bound to any local IP address. Depending on the destination address and the content of the routing table, the system will pick an appropriate source address and replace the "any" binding with a binding to the chosen source IP address.

By default, no two sockets can be bound to the same combination of source address and source port. As long as the source port is different, the source address is actually irrelevant. Binding socketA to ipA:portA and socketB to ipB:portB is always possible if ipA != ipB holds true, even when portA == portB. E.g. socketA belongs to a FTP server program and is bound to 192.168.0.1:21 and socketB belongs to another FTP server program and is bound to 10.0.0.1:21, both bindings will succeed. Keep in mind, though, that a socket may be locally bound to "any address". If a socket is bound to 0.0.0.0:21, it is bound to all existing local addresses at the same time and in that case no other socket can be bound to port 21, regardless which specific IP address it tries to bind to, as 0.0.0.0 conflicts with all existing local IP addresses.

Anything said so far is pretty much equal for all major operating system. Things start to get OS specific when address reuse comes into play. We start with BSD, since as I said above, it is the mother of all socket implementations.

BSD

SO_REUSEADDR

If SO_REUSEADDR is enabled on a socket prior to binding it, the socket can be successfully bound unless there is a conflict with another socket bound to exactly the same combination of source address and port. Now you may wonder how is that any different than before? The keyword is "exactly". SO_REUSEADDR mainly changes the way how wildcard addresses ("any IP address") are treated when searching for conflicts.

Without SO_REUSEADDR, binding socketA to 0.0.0.0:21 and then binding socketB to 192.168.0.1:21 will fail (with error EADDRINUSE), since 0.0.0.0 means "any local IP address", thus all local IP addresses are considered in use by this socket and this includes 192.168.0.1, too. With SO_REUSEADDR it will succeed, since 0.0.0.0 and 192.168.0.1 are not exactly the same address, one is a wildcard for all local addresses and the other one is a very specific local address. Note that the statement above is true regardless in which order socketA and socketB are bound; without SO_REUSEADDR it will always fail, with SO_REUSEADDR it will always succeed.

To give you a better overview, let's make a table here and list all possible combinations:

SO_REUSEADDR       socketA        socketB       Result
---------------------------------------------------------------------
  ON/OFF       192.168.0.1:21   192.168.0.1:21    Error (EADDRINUSE)
  ON/OFF       192.168.0.1:21      10.0.0.1:21    OK
  ON/OFF          10.0.0.1:21   192.168.0.1:21    OK
   OFF             0.0.0.0:21   192.168.1.0:21    Error (EADDRINUSE)
   OFF         192.168.1.0:21       0.0.0.0:21    Error (EADDRINUSE)
   ON              0.0.0.0:21   192.168.1.0:21    OK
   ON          192.168.1.0:21       0.0.0.0:21    OK
  ON/OFF           0.0.0.0:21       0.0.0.0:21    Error (EADDRINUSE)

The table above assumes that socketA has already been successfully bound to the address given for socketA, then socketB is created, either gets SO_REUSEADDR set or not, and finally is bound to the address given for socketB. Result is the result of the bind operation for socketB. If the first column says ON/OFF, the value of SO_REUSEADDR is irrelevant to the result.

Okay, SO_REUSEADDR has an effect on wildcard addresses, good to know. Yet that isn't it's only effect it has. There is another well known effect which is also the reason why most people use SO_REUSEADDR in server programs in the first place. For the other important use of this option we have to take a deeper look on how the TCP protocol works.

A socket has a send buffer and if a call to the send() function succeeds, it does not mean that the requested data has actually really been sent out, it only means the data has been added to the send buffer. For UDP sockets, the data is usually sent pretty soon, if not immediately, but for TCP sockets, there can be a relatively long delay between adding data to the send buffer and having the TCP implementation really send that data. As a result, when you close a TCP socket, there may still be pending data in the send buffer, which has not been sent yet but your code considers it as sent, since the send() call succeeded. If the TCP implementation was closing the socket immediately on your request, all of this data would be lost and your code wouldn't even know about that. TCP is said to be a reliable protocol and losing data just like that is not very reliable. That's why a socket that still has data to send will go into a state called TIME_WAIT when you close it. In that state it will wait until all pending data has been successfully sent or until a timeout is hit, in which case the socket is closed forcefully.

At most, the amount of time the kernel will wait before it closes the socket, regardless if it still has data in flight or not, is called the Linger Time. The Linger Time is globally configurable on most systems and by default rather long (two minutes is a common value you will find on many systems). It is also configurable per socket using the socket option SO_LINGER which can be used to make the timeout shorter or longer, and even to disable it completely. Disabling it completely is a very bad idea, though, since closing a TCP socket gracefully is a slightly complex process and involves sending forth and back a couple of packets (as well as resending those packets in case they got lost) and this whole close process is also limited by the Linger Time. If you disable lingering, your socket may not only lose data in flight, it is also always closed forcefully instead of gracefully, which is usually not recommended. The details about how a TCP connection is closed gracefully are beyond the scope of this answer, if you want to learn more about, I recommend you have a look at this page. And even if you disabled lingering with SO_LINGER, if your process dies without explicitly closing the socket, BSD (and possibly other systems) will linger nonetheless, ignoring what you have configured. This will happen for example if your code just calls exit() (pretty common for tiny, simple server programs) or the process is killed by a signal (which includes the possibility that it simply crashes because of an illegal memory access). So there is nothing you can do to make sure a socket will never linger under all circumstances.

The question is, how does the system treat a socket in state TIME_WAIT? If SO_REUSEADDR is not set, a socket in state TIME_WAIT is considered to still be bound to the source address and port and any attempt to bind a new socket to the same address and port will fail until the socket has really been closed, which may take as long as the configured Linger Time. So don't expect that you can rebind the source address of a socket immediately after closing it. In most cases this will fail. However, if SO_REUSEADDR is set for the socket you are trying to bind, another socket bound to the same address and port in state TIME_WAIT is simply ignored, after all its already "half dead", and your socket can bind to exactly the same address without any problem. In that case it plays no role that the other socket may have exactly the same address and port. Note that binding a socket to exactly the same address and port as a dying socket in TIME_WAIT state can have unexpected, and usually undesired, side effects in case the other socket is still "at work", but that is beyond the scope of this answer and fortunately those side effects are rather rare in practice.

There is one final thing you should know about SO_REUSEADDR. Everything written above will work as long as the socket you want to bind to has address reuse enabled. It is not necessary that the other socket, the one which is already bound or is in a TIME_WAIT state, also had this flag set when it was bound. The code that decides if the bind will succeed or fail only inspects the SO_REUSEADDR flag of the socket fed into the bind() call, for all other sockets inspected, this flag is not even looked at.

SO_REUSEPORT

SO_REUSEPORT is what most people would expect SO_REUSEADDR to be. Basically, SO_REUSEPORT allows you to bind an arbitrary number of sockets to exactly the same source address and port as long as all prior bound sockets also had SO_REUSEPORT set before they were bound. If the first socket that is bound to an address and port does not have SO_REUSEPORT set, no other socket can be bound to exactly the same address and port, regardless if this other socket has SO_REUSEPORT set or not, until the first socket releases its binding again. Unlike in case of SO_REUESADDR the code handling SO_REUSEPORT will not only verify that the currently bound socket has SO_REUSEPORT set but it will also verify that the socket with a conflicting address and port had SO_REUSEPORT set when it was bound.

SO_REUSEPORT does not imply SO_REUSEADDR. This means if a socket did not have SO_REUSEPORT set when it was bound and another socket has SO_REUSEPORT set when it is bound to exactly the same address and port, the bind fails, which is expected, but it also fails if the other socket is already dying and is in TIME_WAIT state. To be able to bind a socket to the same addresses and port as another socket in TIME_WAIT state requires either SO_REUSEADDR to be set on that socket or SO_REUSEPORT must have been set on both sockets prior to binding them. Of course it is allowed to set both, SO_REUSEPORT and SO_REUSEADDR, on a socket.

There is not much more to say about SO_REUSEPORT other than that it was added later than SO_REUSEADDR, that's why you will not find it in many socket implementations of other systems, which "forked" the BSD code before this option was added, and that there was no way to bind two sockets to exactly the same socket address in BSD prior to this option.

Connect() Returning EADDRINUSE?

Most people know that bind() may fail with the error EADDRINUSE, however, when you start playing around with address reuse, you may run into the strange situation that connect() fails with that error as well. How can this be? How can a remote address, after all that's what connect adds to a socket, be already in use? Connecting multiple sockets to exactly the same remote address has never been a problem before, so what's going wrong here?

As I said on the very top of my reply, a connection is defined by a tuple of five values, remember? And I also said, that these five values must be unique otherwise the system cannot distinguish two connections any longer, right? Well, with address reuse, you can bind two sockets of the same protocol to the same source address and port. That means three of those five values are already the same for these two sockets. If you now try to connect both of these sockets also to the same destination address and port, you would create two connected sockets, whose tuples are absolutely identical. This cannot work, at least not for TCP connections (UDP connections are no real connections anyway). If data arrived for either one of the two connections, the system could not tell which connection the data belongs to. At least the destination address or destination port must be different for either connection, so that the system has no problem to identify to which connection incoming data belongs to.

So if you bind two sockets of the same protocol to the same source address and port and try to connect them both to the same destination address and port, connect() will actually fail with the error EADDRINUSE for the second socket you try to connect, which means that a socket with an identical tuple of five values is already connected.

Multicast Addresses

Most people ignore the fact that multicast addresses exist, but they do exist. While unicast addresses are used for one-to-one communication, multicast addresses are used for one-to-many communication. Most people got aware of multicast addresses when they learned about IPv6 but multicast addresses also existed in IPv4, even though this feature was never widely used on the public Internet.

The meaning of SO_REUSEADDR changes for multicast addresses as it allows multiple sockets to be bound to exactly the same combination of source multicast address and port. In other words, for multicast addresses SO_REUSEADDR behaves exactly as SO_REUSEPORT for unicast addresses. Actually, the code treats SO_REUSEADDR and SO_REUSEPORT identically for multicast addresses, that means you could say that SO_REUSEADDR implies SO_REUSEPORT for all multicast addresses and the other way round.

FreeBSD/OpenBSD/NetBSD

All these are rather late forks of the original BSD code, that's why they all three offer the same options as BSD and they also behave the same way as in BSD.

macOS (MacOS X)

At its core, macOS is simply a BSD-style UNIX named "Darwin", based on a rather late fork of the BSD code (BSD 4.3), which was then later on even re-synchronized with the (at that time current) FreeBSD 5 code base for the Mac OS 10.3 release, so that Apple could gain full POSIX compliance (macOS is POSIX certified). Despite having a microkernel at its core ("Mach"), the rest of the kernel ("XNU") is basically just a BSD kernel, and that's why macOS offers the same options as BSD and they also behave the same way as in BSD.

iOS / watchOS / tvOS

iOS is just a macOS fork with a slightly modified and trimmed kernel, somewhat stripped down user space toolset and a slightly different default framework set. watchOS and tvOS are iOS forks, that are stripped down even further (especially watchOS). To my best knowledge they all behave exactly as macOS does.

Linux

Linux < 3.9

Prior to Linux 3.9, only the option SO_REUSEADDR existed. This option behaves generally the same as in BSD with two important exceptions:

1. As long as a listening (server) TCP socket is bound to a specific port, the SO_REUSEADDR option is entirely ignored for all sockets targeting that port. Binding a second socket to the same port is only possible if it was also possible in BSD without having SO_REUSEADDR set. E.g. you cannot bind to a wildcard address and then to a more specific one or the other way round, both is possible in BSD if you set SO_REUSEADDR. What you can do is you can bind to the same port and two different non-wildcard addresses, as that's always allowed. In this aspect Linux is more restrictive than BSD.

2. The second exception is that for client sockets, this option behaves exactly like SO_REUSEPORT in BSD, as long as both had this flag set before they were bound. The reason for allowing that was simply that it is important to be able to bind multiple sockets to exactly to the same UDP socket address for various protocols and as there used to be no SO_REUSEPORT prior to 3.9, the behavior of SO_REUSEADDR was altered accordingly to fill that gap. In that aspect Linux is less restrictive than BSD.

Linux >= 3.9

Linux 3.9 added the option SO_REUSEPORT to Linux as well. This option behaves exactly like the option in BSD and allows binding to exactly the same address and port number as long as all sockets have this option set prior to binding them.

Yet, there are still two differences to SO_REUSEPORT on other systems:

1. To prevent "port hijacking", there is one special limitation: All sockets that want to share the same address and port combination must belong to processes that share the same effective user ID! So one user cannot "steal" ports of another user. This is some special magic to somewhat compensate for the missing SO_EXCLBIND/SO_EXCLUSIVEADDRUSE flags.

2. Additionally the kernel performs some "special magic" for SO_REUSEPORT sockets that isn't found in other operating systems: For UDP sockets, it tries to distribute datagrams evenly, for TCP listening sockets, it tries to distribute incoming connect requests (those accepted by calling accept()) evenly across all the sockets that share the same address and port combination. Thus an application can easily open the same port in multiple child processes and then use SO_REUSEPORT to get a very inexpensive load balancing.

Android

Even though the whole Android system is somewhat different from most Linux distributions, at its core works a slightly modified Linux kernel, thus everything that applies to Linux should apply to Android as well.

Windows

Windows only knows the SO_REUSEADDR option, there is no SO_REUSEPORT. Setting SO_REUSEADDR on a socket in Windows behaves like setting SO_REUSEPORT and SO_REUSEADDR on a socket in BSD, with one exception:

Prior to Windows 2003, a socket with SO_REUSEADDR could always been bound to exactly the same source address and port as an already bound socket, even if the other socket did not have this option set when it was bound. This behavior allowed an application "to steal" the connected port of another application. Needless to say that this has major security implications!

Microsoft realized that and added another important socket option: SO_EXCLUSIVEADDRUSE. Setting SO_EXCLUSIVEADDRUSE on a socket makes sure that if the binding succeeds, the combination of source address and port is owned exclusively by this socket and no other socket can bind to them, not even if it has SO_REUSEADDR set.

This default behavior was changed first in Windows 2003, Microsoft calls that "Enhanced Socket Security" (funny name for a behavior that is default on all other major operating systems). For more details just visit this page. There are three tables: The first one shows the classic behavior (still in use when using compatibility modes!), the second one shows the behavior of Windows 2003 and up when the bind() calls are made by the same user, and the third one when the bind() calls are made by different users.

Solaris

Solaris is the successor of SunOS. SunOS was originally based on a fork of BSD, SunOS 5 and later was based on a fork of SVR4, however SVR4 is a merge of BSD, System V, and Xenix, so up to some degree Solaris is also a BSD fork, and a rather early one. As a result Solaris only knows SO_REUSEADDR, there is no SO_REUSEPORT. The SO_REUSEADDR behaves pretty much the same as it does in BSD. As far as I know there is no way to get the same behavior as SO_REUSEPORT in Solaris, that means it is not possible to bind two sockets to exactly the same address and port.

Similar to Windows, Solaris has an option to give a socket an exclusive binding. This option is named SO_EXCLBIND. If this option is set on a socket prior to binding it, setting SO_REUSEADDR on another socket has no effect if the two sockets are tested for an address conflict. E.g. if socketA is bound to a wildcard address and socketB has SO_REUSEADDR enabled and is bound to a non-wildcard address and the same port as socketA, this bind will normally succeed, unless socketA had SO_EXCLBIND enabled, in which case it will fail regardless the SO_REUSEADDR flag of socketB.

Other Systems

In case your system is not listed above, I wrote a little test program that you can use to find out how your system handles these two options. Also if you think my results are wrong, please first run that program before posting any comments and possibly making false claims.

All that the code requires to build is a bit POSIX API (for the network parts) and a C99 compiler (actually most non-C99 compiler will work as well as long as they offer inttypes.h and stdbool.h; e.g. gcc supported both long before offering full C99 support).

All that the program needs to run is that at least one interface in your system (other than the local interface) has an IP address assigned and that a default route is set which uses that interface. The program will gather that IP address and use it as the second "specific address".

It tests all possible combinations you can think of:

• TCP and UDP protocol
• Normal sockets, listen (server) sockets, multicast sockets
• SO_REUSEADDR set on socket1, socket2, or both sockets
• SO_REUSEPORT set on socket1, socket2, or both sockets
• All address combinations you can make out of 0.0.0.0 (wildcard), 127.0.0.1 (specific address), and the second specific address found at your primary interface (for multicast it's just 224.1.2.3 in all tests)

and prints the results in a nice table. It will also work on systems that don't know SO_REUSEPORT, in which case this option is simply not tested.

What the program cannot easily test is how SO_REUSEADDR acts on sockets in TIME_WAIT state as it's very tricky to force and keep a socket in that state. Fortunately most operating systems seems to simply behave like BSD here and most of the time programmers can simply ignore the existence of that state.

Here's the code (I cannot include it here, answers have a size limit and the code would push this reply over the limit).

On Windows, setting GIT_SSH to openssh that comes with msys git didn't work (Eclipse hung during commit). Setting it to TortoisePlink solved the problem (I guess original plink would work as well). The added bonus is now Eclipse uses keys stored in pageant.

Try:

float x = (float)rand()/(float)(RAND_MAX/a);

To understand how this works consider the following.

N = a random value in [0..RAND_MAX] inclusively.

The above equation (removing the casts for clarity) becomes:

N/(RAND_MAX/a)

But division by a fraction is the equivalent to multiplying by said fraction's reciprocal, so this is equivalent to:

N * (a/RAND_MAX)

which can be rewritten as:

a * (N/RAND_MAX)

Considering N/RAND_MAX is always a floating point value between 0.0 and 1.0, this will generate a value between 0.0 and a.

Alternatively, you can use the following, which effectively does the breakdown I showed above. I actually prefer this simply because it is clearer what is actually going on (to me, anyway):

float x = ((float)rand()/(float)(RAND_MAX)) * a;

Note: the floating point representation of a must be exact or this will never hit your absolute edge case of a (it will get close). See this article for the gritty details about why.

Sample

#include <stdio.h>
#include <stdlib.h>
#include <time.h>

int main(int argc, char *argv[])
{
    srand((unsigned int)time(NULL));

    float a = 5.0;
    for (int i=0;i<20;i++)
        printf("%f\n", ((float)rand()/(float)(RAND_MAX)) * a);
    return 0;
}

For some reasons, this simple problem is blocking many developers. I struggled for many hours with this simple thing. This problem as many dimensions:

1. CORS (if you are using a frontend and backend on different domains et ports.
2. Backend CORS Configuration
3. Basic Authentication configuration of Axios

CORS

My setup for development is with a vuejs webpack application running on localhost:8081 and a spring boot application running on localhost:8080. So when trying to call rest API from the frontend, there's no way that the browser will let me receive a response from the spring backend without proper CORS settings. CORS can be used to relax the Cross Domain Script (XSS) protection that modern browsers have. As I understand this, browsers are protecting your SPA from being an attack by an XSS. Of course, some answers on StackOverflow suggested to add a chrome plugin to disable XSS protection but this really does work AND if it was, would only push the inevitable problem for later.

Backend CORS configuration

Here's how you should setup CORS in your spring boot app:

Add a CorsFilter class to add proper headers in the response to a client request. Access-Control-Allow-Origin and Access-Control-Allow-Headers are the most important thing to have for basic authentication.

    public class CorsFilter implements Filter {

...
    @Override
    public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {
        HttpServletResponse response = (HttpServletResponse) servletResponse;
        HttpServletRequest request = (HttpServletRequest) servletRequest;

        response.setHeader("Access-Control-Allow-Origin", "http://localhost:8081");
        response.setHeader("Access-Control-Allow-Methods", "GET, HEAD, POST, PUT, DELETE, TRACE, OPTIONS, PATCH");
        **response.setHeader("Access-Control-Allow-Headers", "authorization, Content-Type");**
        response.setHeader("Access-Control-Max-Age", "3600");

        filterChain.doFilter(servletRequest, servletResponse);

    }
...
}

Add a configuration class which extends Spring WebSecurityConfigurationAdapter. In this class you will inject your CORS filter:

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
...
    @Bean
    CorsFilter corsFilter() {
        CorsFilter filter = new CorsFilter();
        return filter;
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {

        http.addFilterBefore(corsFilter(), SessionManagementFilter.class) //adds your custom CorsFilter
          .csrf()
          .disable()
          .authorizeRequests()
          .antMatchers("/api/login")
          .permitAll()
          .anyRequest()
          .authenticated()
          .and()
          .httpBasic()
          .authenticationEntryPoint(authenticationEntryPoint)
          .and()
          .authenticationProvider(getProvider());
    }
...
}

You don't have to put anything related to CORS in your controller.

Frontend

Now, in the frontend you need to create your axios query with the Authorization header:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
    <script src="https://unpkg.com/vue"></script>
    <script src="https://unpkg.com/axios/dist/axios.min.js"></script>
</head>
<body>
<div id="app">
    <p>{{ status }}</p>
</div>
<script>
    var vm = new Vue({
        el: "#app",
        data: {
            status: ''
        },
        created: function () {
            this.getBackendResource();
        },
        methods: {
            getBackendResource: function () {
                this.status = 'Loading...';
                var vm = this;
                var user = "aUserName";
                var pass = "aPassword";
                var url = 'http://localhost:8080/api/resource';

                var authorizationBasic = window.btoa(user + ':' + pass);
                var config = {
                    "headers": {
                        "Authorization": "Basic " + authorizationBasic
                    }
                };
                axios.get(url, config)
                    .then(function (response) {
                        vm.status = response.data[0];
                    })
                    .catch(function (error) {
                        vm.status = 'An error occured.' + error;
                    })
            }
        }
    })
</script>
</body>
</html>

Hope this helps.

mvnrepository.com isn't a repository. It's a search engine. It might or might not tell you what repository it found stuff in if it's not central; since you didn't post an example, I can't help you read the output.

//length array now = 0
array[array.length] = 'hello';
//length array now = 1
//            0

you could also use the builtin "join" filter (http://jinja.pocoo.org/docs/templates/#join like this:

Recently, I have tried to develop a simple web app that uses drag and drop components and has lines connecting them. I came across these two simple and amazing javascript libraries:

1. Plain Draggable: simple and high performance library to allow HTML/SVG element to be dragged.
2. Leader Line: Draw a leader line in your web page

Working example link (usage: click on add scene to create a draggable, click on add choice to draw a leader line between two different draggables)

Your approach is good but the problem is that you use "*" instead enlisting fields names. If you put all the columns names excep primary key your script will work like charm on one or many records.

INSERT INTO invoices (iv.field_name, iv.field_name,iv.field_name
) SELECT iv.field_name, iv.field_name,iv.field_name FROM invoices AS iv     
WHERE iv.ID=XXXXX

I believe this would be most correct.

printf("%p", (void *)emp1);
printf("%p", (void *)*emp1);

printf() is a variadic function and must be passed arguments of the right types. The standard says %p takes void *.

Assuming that start_date is before end_date,

interval [start_date..end_date] NOT BETWEEN two dates simply means that either it starts before 2009-12-15 or it ends after 2010-01-02.

Then you can simply do

start_date<CAST('2009-12-15' AS DATE) or end_date>CAST('2010-01-02' AS DATE)

The options for managing tablespaces have got a lot better over the versions starting with 8i. This is especially true if you are using the appropriate types of file for a temporary tablespace (i.e. locally managed tempfiles).

So, it could be as simple as this command, which will shrink your tablespace to 128 meg...

alter tablespace <your_temp_ts> shrink space keep 128M;

The Oracle online documentation is pretty good. Find out more.

edit

It would appear the OP has an earlier version of the database. With earlier versions we have to resize individual datafiles. So, first of all, find the file names. One or other of these queries should do it...

select file_name from dba_data_files where tablespace_name = '<your_temp_ts>'
/

select file_name from dba_temp_files where tablespace_name = '<your_temp_ts>'
/ 

Then use that path in this command:

alter database datafile '/full/file/path/temp01.dbf'  resize 128m
/

I know this is an old thread but it was the first I found when searching. The += solution did not work for me. The code that I did get to work is as below.

#this bit creates the CSV if it does not already exist
$headers = "Name", "Primary Type"
$psObject = New-Object psobject
foreach($header in $headers)
{
 Add-Member -InputObject $psobject -MemberType noteproperty -Name $header -Value ""
}
$psObject | Export-Csv $csvfile -NoTypeInformation

#this bit appends a new row to the CSV file
$bName = "My Name"
$bPrimaryType = "My Primary Type"
    $hash = @{
             "Name" =  $bName
             "Primary Type" = $bPrimaryType
              }

$newRow = New-Object PsObject -Property $hash
Export-Csv $csvfile -inputobject $newrow -append -Force

I was able to use this as a function to loop through a series of arrays and enter the contents into the CSV file.

It works in powershell 3 and above.

If you are unable to get rid of extra xmlns attributes for each element, when serializing to xml from generated classes (e.g.: when xsd.exe was used), so you have something like:

<manyElementWith xmlns="urn:names:specification:schema:xsd:one" />

then i would share with you what worked for me (a mix of previous answers and what i found here)

explicitly set all your different xmlns as follows:

Dim xmlns = New XmlSerializerNamespaces()
xmlns.Add("one", "urn:names:specification:schema:xsd:one")
xmlns.Add("two",  "urn:names:specification:schema:xsd:two")
xmlns.Add("three",  "urn:names:specification:schema:xsd:three")

then pass it to the serialize

serializer.Serialize(writer, object, xmlns);

you will have the three namespaces declared in the root element and no more needed to be generated in the other elements which will be prefixed accordingly

<root xmlns:one="urn:names:specification:schema:xsd:one" ... />
   <one:Element />
   <two:ElementFromAnotherNameSpace /> ...

You can use some code like this, you can adjust a height and width as per your need

    protected void button_Click(object sender, EventArgs e)
    {
        // open a pop up window at the center of the page.
        ScriptManager.RegisterStartupScript(this, typeof(string), "OPEN_WINDOW", "var Mleft = (screen.width/2)-(760/2);var Mtop = (screen.height/2)-(700/2);window.open( 'your_page.aspx', null, 'height=700,width=760,status=yes,toolbar=no,scrollbars=yes,menubar=no,location=no,top=\'+Mtop+\', left=\'+Mleft+\'' );", true);
    }

I think one of the best solutions and easiest is:

strtotime("+30 minutes")

Maybe it's not the most efficient but is one of the more understandable.

This is what you need:

For the first cell of A, this would be:

Here you can find Hardware-Assisted Virtualization Detection Tool ( http://www.microsoft.com/downloads/en/details.aspx?FamilyID=0ee2a17f-8538-4619-8d1c-05d27e11adb2&displaylang=en) which will tell you if your hardware supports VT-x.

Alternatively you can find your processor here: http://ark.intel.com/Default.aspx. All AMD processors since 2006 supports Virtualization.

No, I don't think you can append key/value pairs. The only thing closest that I am aware of is using the store method:

h = {}
h.store("key", "value")

On greedy vs non-greedy

Repetition in regex by default is greedy: they try to match as many reps as possible, and when this doesn't work and they have to backtrack, they try to match one fewer rep at a time, until a match of the whole pattern is found. As a result, when a match finally happens, a greedy repetition would match as many reps as possible.

The ? as a repetition quantifier changes this behavior into non-greedy, also called reluctant (in e.g. Java) (and sometimes "lazy"). In contrast, this repetition will first try to match as few reps as possible, and when this doesn't work and they have to backtrack, they start matching one more rept a time. As a result, when a match finally happens, a reluctant repetition would match as few reps as possible.

• regular-expressions.info/Repetition - Laziness instead of Greediness

Example 1: From A to Z

Let's compare these two patterns: A.*Z and A.*?Z.

Given the following input:

eeeAiiZuuuuAoooZeeee

The patterns yield the following matches:

• A.*Z yields 1 match: AiiZuuuuAoooZ (see on rubular.com)
• A.*?Z yields 2 matches: AiiZ and AoooZ (see on rubular.com)

Let's first focus on what A.*Z does. When it matched the first A, the .*, being greedy, first tries to match as many . as possible.

eeeAiiZuuuuAoooZeeee
   \_______________/
    A.* matched, Z can't match

Since the Z doesn't match, the engine backtracks, and .* must then match one fewer .:

eeeAiiZuuuuAoooZeeee
   \______________/
    A.* matched, Z still can't match

This happens a few more times, until finally we come to this:

eeeAiiZuuuuAoooZeeee
   \__________/
    A.* matched, Z can now match

Now Z can match, so the overall pattern matches:

eeeAiiZuuuuAoooZeeee
   \___________/
    A.*Z matched

By contrast, the reluctant repetition in A.*?Z first matches as few . as possible, and then taking more . as necessary. This explains why it finds two matches in the input.

Here's a visual representation of what the two patterns matched:

eeeAiiZuuuuAoooZeeee
   \__/r   \___/r      r = reluctant
    \____g____/        g = greedy

Example: An alternative

In many applications, the two matches in the above input is what is desired, thus a reluctant .*? is used instead of the greedy .* to prevent overmatching. For this particular pattern, however, there is a better alternative, using negated character class.

The pattern A[^Z]*Z also finds the same two matches as the A.*?Z pattern for the above input (as seen on ideone.com). [^Z] is what is called a negated character class: it matches anything but Z.

The main difference between the two patterns is in performance: being more strict, the negated character class can only match one way for a given input. It doesn't matter if you use greedy or reluctant modifier for this pattern. In fact, in some flavors, you can do even better and use what is called possessive quantifier, which doesn't backtrack at all.

References

• regular-expressions.info/Repetition - An Alternative to Laziness, Negated Character Classes and Possessive Quantifiers

Example 2: From A to ZZ

This example should be illustrative: it shows how the greedy, reluctant, and negated character class patterns match differently given the same input.

eeAiiZooAuuZZeeeZZfff

These are the matches for the above input:

• A[^Z]*ZZ yields 1 match: AuuZZ (as seen on ideone.com)
• A.*?ZZ yields 1 match: AiiZooAuuZZ (as seen on ideone.com)
• A.*ZZ yields 1 match: AiiZooAuuZZeeeZZ (as seen on ideone.com)

Here's a visual representation of what they matched:

         ___n
        /   \              n = negated character class
eeAiiZooAuuZZeeeZZfff      r = reluctant
  \_________/r   /         g = greedy
   \____________/g

One greedy repetition can outgreed another

• Regex not being greedy enough
• Regular expression: who's greedier

Frustratingly, you have to enable showing the dividers from code in your activity. For example:

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    // Set the view to your layout
    setContentView(R.layout.yourlayout);

    // Find the LinearLayout within and enable the divider
    ((LinearLayout)v.findViewById(R.id.llTopBar)).
        setShowDividers(LinearLayout.SHOW_DIVIDER_MIDDLE);

}

In my case I was updating a loading state that was passed down to a component. Within the Button the props.loading was coming through as expected (switching from false to true) but the ternary that showed a spinner wasn't updating.

I tried adding a key, adding a state that updated with useEffect() etc but none of the other answers worked.

What worked for me was changing this:

setLoading(true);
handleOtherCPUHeavyCode();

To this:

setLoading(true);
setTimeout(() => { handleOtherCPUHeavyCode() }, 1)

I assume it's because the process in handleOtherCPUHeavyCode is pretty heavy and intensive so the app freezes for a second or so. Adding the 1ms timeout allows the loading boolean to update and then the heavy code function can do it's work.

Using ex/vi editor and globstar option (syntax similar to awk and sed):

ex +"/string1/,/string3/p" -R -scq! file.txt

where aaa is your starting point, and bbb is your ending text.

To search recursively, try:

ex +"/aaa/,/bbb/p" -scq! **/*.py

^{Note: To enable ** syntax, run shopt -s globstar (Bash 4 or zsh).}

This regex selects all spaces, you can use this and replace it with a single space

\s+

example in python

result = re.sub('\s+',' ', data))

Don't use doubles. You can lose some precision. Here's a general purpose function.

public static double round(double unrounded, int precision, int roundingMode)
{
    BigDecimal bd = new BigDecimal(unrounded);
    BigDecimal rounded = bd.setScale(precision, roundingMode);
    return rounded.doubleValue();
}

You can call it with

round(yourNumber, 3, BigDecimal.ROUND_HALF_UP);

"precision" being the number of decimal points you desire.

opt is new for ruby 1.9. The various options are documented in IO.new : www.ruby-doc.org/core/IO.html

Navigate to /tomcat-root/conf folder. Within you will find the server.xml file.

Open the server.xml in your preferred editor. Search the below similar statement (not exactly same as below will differ)

    <Connector port="8080" protocol="HTTP/1.1" 
           connectionTimeout="20000" 
           redirectPort="8443" />

Going to give the port number to 9090

     <Connector port="9090" protocol="HTTP/1.1" 
           connectionTimeout="20000" 
           redirectPort="8443" />

Save the file and restart the server. Now the tomcat will listen at port 9090

You need to trigger the onChange event manually. On text inputs onChange listens for input events.

So in you handleClick function you need to trigger event like

handleClick () {
    this.setState({value: 'another random text'})
    var event = new Event('input', { bubbles: true });
    this.myinput.dispatchEvent(event);
  }

Complete code

class App extends React.Component {
  constructor(props) {
    super(props)
    this.state = {
    value: 'random text'
    }
  }
  handleChange (e) {
    console.log('handle change called')
  }
  handleClick () {
    this.setState({value: 'another random text'})
    var event = new Event('input', { bubbles: true });
    this.myinput.dispatchEvent(event);
  }
  render () {
    return (
      <div>
        <input readOnly value={this.state.value} onChange={(e) => {this.handleChange(e)}} ref={(input)=> this.myinput = input}/>
        <button onClick={this.handleClick.bind(this)}>Change Input</button>
      </div>
    )
  }
}

ReactDOM.render(<App />,  document.getElementById('app'))

Codepen

Edit: As Suggested by @Samuel in the comments, a simpler way would be to call handleChange from handleClick if you don't need to the event object in handleChange like

handleClick () {
    this.setState({value: 'another random text'})
    this.handleChange();
  }

I hope this is what you need and it helps you.

I agree with what @fge said, more over. Lets look at example. Consider you have a method:

class A {
    public void foo(OtherClass other) {
        SomeData data = new SomeData("Some inner data");
        other.doSomething(data);
    }
}

Now if you want to check the inner data you can use the captor:

// Create a mock of the OtherClass
OtherClass other = mock(OtherClass.class);

// Run the foo method with the mock
new A().foo(other);

// Capture the argument of the doSomething function
ArgumentCaptor<SomeData> captor = ArgumentCaptor.forClass(SomeData.class);
verify(other, times(1)).doSomething(captor.capture());

// Assert the argument
SomeData actual = captor.getValue();
assertEquals("Some inner data", actual.innerData);

On button click you can try the following.

protected void button1_Click(object sender, EventArgs e)
{
     Response.Redirect("~/Admin/Admin.aspx");
}

And on PageLoad you can check whether the loading is coming from that button then increase the count.

       protected void Page_Load(object sender, EventArgs e)
         {
            StackTrace stackTrace = new StackTrace();
            string eventName = stackTrace.GetFrame(1).GetMethod().Name; // this will the event name.
            if (eventName == "button1_Click")
              {
                // code to increase the count;
              }
          }

Thanks

select count(*) 
from user_tab_columns
where table_name='MYTABLE' --use upper case

Instead of uppercase you can use lower function. Ex: select count(*) from user_tab_columns where lower(table_name)='table_name';

Actually the enhanced for loop should look like this

for (final Room room : rooms) {
          // Here your room is available
}

I'm the author of the article in question.

No doubt there are multiple ways to do it, but the way I typically do it is to implement a custom UserDetails that knows about roles and permissions. Role and Permission are just custom classes that you write. (Nothing fancy--Role has a name and a set of Permission instances, and Permission has a name.) Then the getAuthorities() returns GrantedAuthority objects that look like this:

PERM_CREATE_POST, PERM_UPDATE_POST, PERM_READ_POST

instead of returning things like

ROLE_USER, ROLE_MODERATOR

The roles are still available if your UserDetails implementation has a getRoles() method. (I recommend having one.)

Ideally you assign roles to the user and the associated permissions are filled in automatically. This would involve having a custom UserDetailsService that knows how to perform that mapping, and all it has to do is source the mapping from the database. (See the article for the schema.)

Then you can define your authorization rules in terms of permissions instead of roles.

Hope that helps.

People.OrderBy(p => p.DateOfBirth.GetValueOrDefault(DateTime.MaxValue)).First()

Would do the trick

An Int (or TinyInt) aligned to an Enum field would be my methodology.

First, if you have a single bit field in a database, the row will still use a full byte, so as far as space savings, it only pays off if you have multiple bit fields.

Second, strings/chars have a "magic value" feel to them, regardless of how obvious they may seem at design time. Not to mention, it lets people store just about any value they would not necessarily map to anything obvious.

Third, a numeric value is much easier (and better practice) to create a lookup table for, in order to enforce referential integrity, and can correlate 1-to-1 with an enum, so there is parity in storing the value in memory within the application or in the database.

Use:

enter code var moment = require('moment')
var startDate = moment('2013-5-11 8:73:18', 'YYYY-M-DD HH:mm:ss')

Moment.js works very well. You can read more about it here.

Is there a specific reason you want to use FileNameExtensionFilter? I know this works..

private File[] getNewTextFiles() {
    return dir.listFiles(new FilenameFilter() {
        @Override
        public boolean accept(File dir, String name) {
            return name.toLowerCase().endsWith(".txt");
        }
    });
}

TL;DR: use one PNG icon at 180 x 180 px @ 150 ppi and then link to it like this:

<link rel="apple-touch-icon" href="path/to/apple-touch-icon.png">

Details on the Approach

As of 2020-04, the canonical response from Apple is reflected in their documentation on iOS.

Officially, the spec says:

• iPhone 180px × 180px (60pt × 60pt @3x)
• iPhone 120px × 120px (60pt × 60pt @2x)
• iPad Pro 167px × 167px (83.5pt × 83.5pt @2x)
• iPad, iPad mini 152px × 152px (76pt × 76pt @2x)

In reality, these sizing differences are tiny, so the performance savings will really only matter on very high traffic sites.

For lower traffic sites, I typically use one PNG icon at 180 x 180 px @ 150 ppi and get very good results on all devices, even the plus sized ones.

It's related about revert origin : to set origin when the object is drag : just use $(this).data("draggable").originalPosition = {top:0, left:0};

For example : i use like this

               drag: function() {
                    var t = $(this);
                    left = parseInt(t.css("left")) * -1;
                    if(left > 0 ){
                        left = 0;
                        t.draggable( "option", "revert", true );
                        $(this).data("draggable").originalPosition = {top:0, left:0};
                    } 
                    else t.draggable( "option", "revert", false );

                    $(".slider-work").css("left",  left);
                }

public string strConnectionstring = "Data Source=(LocalDB)\\MSSQLLocalDB;AttachDbFilename=|DataDirectory|\\DataBaseName.mdf";

I think we should to have a consideration about the necessity of parent to use the child’s methods.In fact,parents needn’t to concern the method of child,but can treat the child component as a FSA(finite state machine).Parents component to control the state of child component.So the solution to watch the status change or just use the compute function is enough

Most of the answers for this question can not helped me in 2020.

This notification from download site of Oracle may be the reason:

Important Oracle JDK License Update

The Oracle JDK License has changed for releases starting April 16, 2019.

I try to google a little bit and those tutorials below helped me a lot.

1. Remove completely the previous version of JVM installed on your PC.

   sudo update-alternatives --remove-all java
   sudo update-alternatives --remove-all javac
   sudo update-alternatives --remove-all javaws
   
   # /usr/lib/jvm/jdk1.7.0 is the path you installed the previous version of JVM on your PC
   sudo rm -rf /usr/lib/jvm/jdk1.7.0 
   

   Check to see whether java is uninstalled or not

   java -version
   

2. Install Java 8 JDK.

   • Download Java 8 from Oracle's website. The version being used is 1.8.0_251. Pay attention to this value, you may need it to edit commands in this answer when Java 8 is upgraded to another version.
   • Extract the compressed file to the place where you want to install.

   cd /usr/lib/jvm
   sudo tar xzf ~/Downloads/jdk-8u251-linux-x64.tar.gz
   

   • Edit environment file

   sudo gedit /etc/environment
   

   • Edit the PATH's value by appending the string below to the current value

   :/usr/lib/jvm/jdk1.8.0_251/bin:/usr/lib/jvm/jdk1.8.0_251/jre/bin
   

   • Append those strings to the environment file

   J2SDKDIR="/usr/lib/jvm/jdk1.8.0_251"
   J2REDIR="/usr/lib/jvm/jdk1.8.0_251/jre"
   JAVA_HOME="/usr/lib/jvm/jdk1.8.0_251"
   

   • Complete the installation by running commands below

   sudo update-alternatives --install "/usr/bin/java" "java" "/usr/lib/jvm/jdk1.8.0_251/bin/java" 0
   sudo update-alternatives --install "/usr/bin/javac" "javac" "/usr/lib/jvm/jdk1.8.0_251/bin/javac" 0
   sudo update-alternatives --set java /usr/lib/jvm/jdk1.8.0_251/bin/java
   sudo update-alternatives --set javac /usr/lib/jvm/jdk1.8.0_251/bin/javac
   
   update-alternatives --list java
   update-alternatives --list javac
   

You can always use iptables to delete the rules. If you have a lot of rules, just output them using the following command.

iptables-save > myfile

vi to edit them from the commend line. Just use the "dd" to delete the lines you no longer want.

iptables-restore < myfile and you're good to go.  

REMEMBER THAT IF YOU DON'T CONFIGURE YOUR OS TO SAVE THE RULES TO A FILE AND THEN LOAD THE FILE DURING THE BOOT THAT YOUR RULES WILL BE LOST.

If I understood your question, try something like this

declare @dd varchar(50)='Jan 30 2013 12:00:00:000AM'

Select convert(varchar,(CONVERT(date,@dd,103)),103)

Update

SELECT
PREFIX_TableName.ColumnName1 AS Name,
PREFIX_TableName.ColumnName2 AS E-Mail,
convert(varchar,(CONVERT(date,PREFIX_TableName.ColumnName3,103)),103) AS TransactionDate,
PREFIX_TableName.ColumnName4 AS OrderNumber

I only partially agree with the top rated answer for this question. Which type of testing would you say should be the emphasis (for testers/QAs), and why?

1. I agree that: "Black box testing should be the emphasis for testers/QA."
2. I agree that White box testing should be the emphasis for developers, but I don't agree that White Box testing is just unit tests.

I agree with the definition here which states that White Box Testing method is applicable to the following levels of software testing:

• Unit Testing: For testing paths within a unit
• Integration Testing:For testing paths between units
• System Testing: For testing paths between subsystems

Check your DB_HOST on your .env file

DB_HOST=http://localhost/ --> DB_HOST=localhost

php artisan config:clear it will help you, clear cached config

Use this:

word = raw_input("Please enter a single word : ")
while True:
    if " " in word:
        word = raw_input("Please enter a single word : ")
    else:
        print "Thanks"
        break

Because SQL Server performs integer division. Try this:

select 1 * 1.0 / 3

This is helpful when you pass integers as params.

select x * 1.0 / y

Ok, I deleted my previous answer because finally it was not what willlangford was looking for, but I made my point that maybe we were all misunderstanding the question.

I also thought of the SELECT DISTINCT... thing at first, but it seemed too weird to me that someone needed to know how many people had a different number of pets than the rest... thats why I thought that maybe the question was not clear enough.

So, now that the real question meaning is clarified, making a subquery for this its quite an overhead, I would preferably use a GROUP BY clause.

Imagine you have the table customer_pets like this:

+-----------------------+
|  customer  |   pets   |
+------------+----------+
| customer1  |    2     |
| customer2  |    3     |
| customer3  |    2     |
| customer4  |    2     |
| customer5  |    3     |
| customer6  |    4     |
+------------+----------+

then

SELECT count(customer) AS num_customers, pets FROM customer_pets GROUP BY pets

would return:

+----------------------------+
|  num_customers  |   pets   |
+-----------------+----------+
|        3        |    2     |
|        2        |    3     |
|        1        |    4     |
+-----------------+----------+

as you need.

You can either do 1 of the following:

Change:

SET @UserId = 0 to SELECT @UserId

This will return the value in the same way your 2nd part of the IF statement is.

Or, seeing as @UserId is set as an Output, change:

SELECT SCOPE_IDENTITY() to SET @UserId = SCOPE_IDENTITY()

It depends on how you want to access the data afterwards. If you want the value to be in your result set, use SELECT. If you want to access the new value of the @UserId parameter afterwards, then use SET @UserId

Seeing as you're accepting the 2nd condition as correct, the query you could write (without having to change anything outside of this query) is:

@EmailAddress varchar(200),
@NickName varchar(100),
@Password varchar(150),
@Sex varchar(50),
@Age int,
@EmailUpdates int,
@UserId int OUTPUT
IF 
    (SELECT COUNT(UserId) FROM RegUsers WHERE EmailAddress = @EmailAddress) > 0
    BEGIN
        SELECT 0
    END
ELSE
    BEGIN
        INSERT INTO RegUsers (EmailAddress,NickName,PassWord,Sex,Age,EmailUpdates) VALUES (@EmailAddress,@NickName,@Password,@Sex,@Age,@EmailUpdates)
        SELECT SCOPE_IDENTITY()
    END

END

Your CAST() looks correct.

Your CONVERT() is not correct. You are quoting the column as a string. You will want something like

CONVERT(INT, A.my_NvarcharColumn)

** notice without the quotes **

The only other reason why this could fail is if you have a non-numeric character in the field value or if it's out of range.

You can try something like the following to verify it's numeric and return a NULL if it's not:

SELECT
 CASE
  WHEN ISNUMERIC(A.my_NvarcharColumn) = 1 THEN CONVERT(INT, A.my_NvarcharColumn)
  ELSE NULL
 END AS my_NvarcharColumn

Jonathon gave you an approach using dict comprehensions in his answer. Here is an approach that deals with your do something part.

If you want to do something with the values of the dictionary, you don't need a dictionary comprehension at all:

I'm using iteritems() since you tagged your question with python-2.7

results = map(some_function, [(k,v) for k,v in a_dict.iteritems() if 'foo' in k])

Now the result will be in a list with some_function applied to each key/value pair of the dictionary, that has foo in its key.

If you just want to deal with the values and ignore the keys, just change the list comprehension:

results = map(some_function, [v for k,v in a_dict.iteritems() if 'foo' in k])

some_function can be any callable, so a lambda would work as well:

results = map(lambda x: x*2, [v for k,v in a_dict.iteritems() if 'foo' in k])

The inner list is actually not required, as you can pass a generator expression to map as well:

>>> map(lambda a: a[0]*a[1], ((k,v) for k,v in {2:2, 3:2}.iteritems() if k == 2))
[4]

I liked the fileinput approach as explained in this answer: Deleting a line from a text file (python)

Say for example I have a file which has empty lines in it and I want to remove empty lines, here's how I solved it:

import fileinput
import sys
for line_number, line in enumerate(fileinput.input('file1.txt', inplace=1)):
    if len(line) > 1:
            sys.stdout.write(line)

Note: The empty lines in my case had length 1

You can use the arguments object property inside the function.

A simple way is.....

#include <stdio.h>
#include <stdlib.h>


#define SHELLSCRIPT "\
#/bin/bash \n\
echo \"hello\" \n\
echo \"how are you\" \n\
echo \"today\" \n\
"
/*Also you can write using char array without using MACRO*/
/*You can do split it with many strings finally concatenate 
  and send to the system(concatenated_string); */

int main()
{
    puts("Will execute sh with the following script :");
    puts(SHELLSCRIPT);
    puts("Starting now:");
    system(SHELLSCRIPT);    //it will run the script inside the c code. 
    return 0;
}

One option that might work is using WindowsIdentity.Impersonate (and change the thread principal) to become the desired user, like so. Back to p/invoke, though, I'm afraid...

Another cheeky (and equally far from ideal) option might be to spawn a process to do the work... ProcessStartInfo accepts a .UserName, .Password and .Domain.

Finally - perhaps run the service in a dedicated account that has access? (removed as you have clarified that this isn't an option).

I met this issue this morning because I used the same executable in DIFFERENT OSes: after compiling my program with gcc -ggdb -Wall test.c -o test in my Mac(10.15.2), I ran gdb with the executable in Ubuntu(16.04) in my VirtualBox.

Fix: recompile with the same command under Ubuntu, then you should be good.

From Android 19, you can register an app life cycle callback in your Application class's onCreate() like this:

@Override
public void onCreate() {
    super.onCreate();
    registerActivityLifecycleCallbacks(new AppLifecycleCallback());
}

The AppLifecycleCallback looks like this:

class AppLifecycleCallback implements Application.ActivityLifecycleCallbacks {
    private int numStarted = 0;

    @Override
    public void onActivityCreated(Activity activity, Bundle savedInstanceState) {

    }

    @Override
    public void onActivityStarted(Activity activity) {
        if (numStarted == 0) {
           //app went to foreground
        }
        numStarted++;
    }

    @Override
    public void onActivityResumed(Activity activity) {

    }

    @Override
    public void onActivityPaused(Activity activity) {

    }

    @Override
    public void onActivityStopped(Activity activity) {
        numStarted--;
        if (numStarted == 0) {
            // app went to background
        }
    }

    @Override
    public void onActivitySaveInstanceState(Activity activity, Bundle outState) {

    }

    @Override
    public void onActivityDestroyed(Activity activity) {

    }
}

In case you did changes to your context and you want to manually make relevant changes to DB (or leave it as is), there is a fast and dirty way.

Go to DB, and delete everything from "_MigrationHistory" table

Following should work. I have verified. May be your problem is somewhere else.

Receiver:

public class MyReceiver extends BroadcastReceiver{

    @Override
    public void onReceive(Context context, Intent intent) {
        if (Intent.ACTION_BOOT_COMPLETED.equals(arg1.getAction())) {
            Log.d("TAG", "MyReceiver");
            Intent serviceIntent = new Intent(context, Test1Service.class);
            context.startService(serviceIntent);
        }
    }
}

Service:

public class Test1Service extends Service {
    /** Called when the activity is first created. */
    @Override
    public void onCreate() {
        super.onCreate();
        Log.d("TAG", "Service created.");
    }
    
    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        Log.d("TAG", "Service started.");
        return super.onStartCommand(intent, flags, startId);
    }
    
    @Override
    public void onStart(Intent intent, int startId) {
        super.onStart(intent, startId);
        Log.d("TAG", "Service started.");
    }
    @Override
    public IBinder onBind(Intent arg0) {
        return null;
    }
}

You've installed the version of git-completion.bash from master - in git's development history this is after a commit that split out the __git_ps1 function from the completion functionality into a new file (git-prompt.sh). The commit that introduced this change, which explains the rationale, is af31a456.

I would still suggest that you just source the version of git-completion.bash (or git-prompt.sh) that is bundled with your installation of git.

However, if for some reason you still want to use this functionality by using scripts separately downloaded from master, you should download git-prompt.sh similarly:

curl -o ~/.git-prompt.sh \
    https://raw.githubusercontent.com/git/git/master/contrib/completion/git-prompt.sh

... and add the following line to your ~/.bash_profile:

source ~/.git-prompt.sh

Then your PS1 variable that includes __git_ps1 '%s' should work fine.

The package "tictoc" gives you a very simple way of measuring execution time. The documentation is in: https://cran.fhcrc.org/web/packages/tictoc/tictoc.pdf.

install.packages("tictoc")
require(tictoc)
tic()
rnorm(1000,0,1)
toc()

To save the elapsed time into a variable you can do:

install.packages("tictoc")
require(tictoc)
tic()
rnorm(1000,0,1)
exectime <- toc()
exectime <- exectime$toc - exectime$tic

that's in .scss

I have Windows 8.1, Eclipse Neon, Tomcat 8.

The solution is to copy all the files from folder ".../Tomcatxxx/conf" to the ".../Workspace_directory/Servers" and try to launch server again.

I used angular with electron,

In my case, setInterval returns a Nodejs Timer object. which when I called clearInterval(timerobject) it did not work.

I had to get the id first and call to clearInterval

clearInterval(timerobject._id)

I have struggled many hours with this. hope this helps.

Take a look at my solution here, it should work. The idea is to remove all the unwanted symbols from the words, then separate those words and store them in some other variable, i was using ArrayList. By adjusting the "excludedSymbols" variable you can add more symbols which you would like to be excluded from the words.

public static void countWords () {
    String textFileLocation ="c:\\yourFileLocation";
    String readWords ="";
    ArrayList<String> extractOnlyWordsFromTextFile = new ArrayList<>();
    // excludedSymbols can be extended to whatever you want to exclude from the file 
    String[] excludedSymbols = {" ", "," , "." , "/" , ":" , ";" , "<" , ">", "\n"};
    String readByteCharByChar = "";
    boolean testIfWord = false;


    try {
        InputStream inputStream = new FileInputStream(textFileLocation);
        byte byte1 = (byte) inputStream.read();
        while (byte1 != -1) {

            readByteCharByChar +=String.valueOf((char)byte1);
            for(int i=0;i<excludedSymbols.length;i++) {
            if(readByteCharByChar.equals(excludedSymbols[i])) {
                if(!readWords.equals("")) {
                extractOnlyWordsFromTextFile.add(readWords);
                }
                readWords ="";
                testIfWord = true;
                break;
            }
            }
            if(!testIfWord) {
                readWords+=(char)byte1;
            }
            readByteCharByChar = "";
            testIfWord = false;
            byte1 = (byte)inputStream.read();
            if(byte1 == -1 && !readWords.equals("")) {
                extractOnlyWordsFromTextFile.add(readWords);
            }
        }
        inputStream.close();
        System.out.println(extractOnlyWordsFromTextFile);
        System.out.println("The number of words in the choosen text file are: " + extractOnlyWordsFromTextFile.size());
    } catch (IOException ioException) {

        ioException.printStackTrace();
    }
}

        // Example: Adding a converter to a column (C#)
        Style styleReading = new Style(typeof(TextBlock));
        Setter s = new Setter();
        s.Property = TextBlock.ForegroundProperty;
        Binding b = new Binding();
        b.RelativeSource = RelativeSource.Self;
        b.Path = new PropertyPath(TextBlock.TextProperty);
        b.Converter = new ReadingForegroundSetter();
        s.Value = b;
        styleReading.Setters.Add(s);
        col.ElementStyle = styleReading;

This happened to me when carrying out manual tests of the sign up process of my application (signing up/in with multiple users).

A very simple and pragmatic solution may be to do what I did, and use a different browser (or incognito if using chrome).

This was a much better solution in my case than disabling security features!!

Purpose of view is displaying model. You should use controller to redirect request before creating model and passing it to view. Use Controller.RedirectToAction method for this.

You can try doing a replace of #region with \n, turning extended search mode on.

You can download Application Loader from Itunes Connect.

Addressing the question as updated.

#...part of script without redirection...

{
    #...part of script with redirection...
} > file1 2>file2 # ...and others as appropriate...

#...residue of script without redirection...

The braces '{ ... }' provide a unit of I/O redirection. The braces must appear where a command could appear - simplistically, at the start of a line or after a semi-colon. (Yes, that can be made more precise; if you want to quibble, let me know.)

You are right that you can preserve the original stdout and stderr with the redirections you showed, but it is usually simpler for the people who have to maintain the script later to understand what's going on if you scope the redirected code as shown above.

The relevant sections of the Bash manual are Grouping Commands and I/O Redirection. The relevant sections of the POSIX shell specification are Compound Commands and I/O Redirection. Bash has some extra notations, but is otherwise similar to the POSIX shell specification.

I've just found this solution:

if(@getimagesize($remoteImageURL)){
    //image exists!
}else{
    //image does not exist.
}

The etckeeper tool can handle permissions and with:

etckeeper init -d /mydir

You can use it for other dirs than /etc.

Install by using your package manager or get sources from above link.

Assuming that yourObject.toString() returns "true" or "false", you can try

boolean b = Boolean.valueOf(yourObject.toString())

995 is an error reported by the IO Completion Port. The error comes since you try to continue read from the socket when it has most likely been closed.

Receiving 0 bytes from EndRecieve means that the socket has been closed, as does most exceptions that EndRecieve will throw.

You need to start dealing with those situations.

Never ever ignore exceptions, they are thrown for a reason.

Update

There is nothing that says that the server does anything wrong. A connection can be lost for a lot of reasons such as idle connection being closed by a switch/router/firewall, shaky network, bad cables etc.

What I'm saying is that you MUST handle disconnections. The proper way of doing so is to dispose the socket and try to connect a new one at certain intervals.

As for the receive callback a more proper way of handling it is something like this (semi pseudo code):

public void OnDataReceived(IAsyncResult asyn)
{
    BLCommonFunctions.WriteLogger(0, "In :- OnDataReceived", ref swReceivedLogWriter, strLogPath, 0);

    try
    {
        SocketPacket client = (SocketPacket)asyn.AsyncState;

        int bytesReceived = client.thisSocket.EndReceive(asyn); //Here error is coming
        if (bytesReceived == 0)
        {
          HandleDisconnect(client);
          return;
        }
    }
    catch (Exception err)
    {
       HandleDisconnect(client);
    }

    try
    {
        string strHEX = BLCommonFunctions.ByteArrToHex(theSockId.dataBuffer);                    

        //do your handling here
    }
    catch (Exception err)
    {
        // Your logic threw an exception. handle it accordinhly
    }

    try
    {
       client.thisSocket.BeginRecieve(.. all parameters ..);
    }
    catch (Exception err)
    {
       HandleDisconnect(client);
    }
}

the reason to why I'm using three catch blocks is simply because the logic for the middle one is different from the other two. Exceptions from BeginReceive/EndReceive usually indicates socket disconnection while exceptions from your logic should not stop the socket receiving.

bool hasErrors =  ViewData.ModelState.Values.Any(x => x.Errors.Count > 1);

or iterate with

    foreach (ModelState state in ViewData.ModelState.Values.Where(x => x.Errors.Count > 0))
    {

    }

I got same problem... and I did it.

My code before:

<link rel="stylesheet" href="../css/style.default.css" type="text/css" />

And the problem solved after I changed my code into this:

<link rel="stylesheet" href="css/style.default.css" type="text/css" />

So I think "href=../" is not allowed, because I don't have problem when I use "../" in "src=../"

You can create a putty session, and auto load the script on the server, when starting the session:

putty -load "sessionName" 

At remote command, point to the remote script.

You will need to change your compiler compliance level back to 1.7 in your IDE.

This can be done in the preferences settings of your IDE. For example, in Eclipse go to menu Windows ? Preferences, select Java, and expand it. Then select Compiler and change the compliance level to 1.7. I am sure this will work from there.

I managed to fix Vue Cli no command error by doing the following:

• In terminal sudo nano ~/.bash_profile to edit your bash profile.
• Add export PATH=$PATH:/Users/[your username]/.npm-packages/bin
• Save file and restart terminal
• Now you should be able to use vue create my-project and vue --version etc.

I did this after I installed the latest Vue Cli from https://cli.vuejs.org/

I generally use yarn, but I installed this globally with npm npm install -g @vue/cli. You can use yarn too if you'd like yarn global add @vue/cli

Note: you may have to uninstall it first globally if you already have it installed: npm uninstall -g vue-cli

Hope this helps!

If you want to sort data either in Ascending or Descending order based on particular column, using sequlize js, use the order method of sequlize as follows

// Will order the specified column by descending order
order: sequelize.literal('column_name order')
e.g. order: sequelize.literal('timestamp DESC')

You could use a SVG drawing instead of a Canvas drawing. There you can add events directly to the drawn DOM objects.

see for example:

mappedby speaks for itself, it tells hibernate not to map this field. it's already mapped by this field [name="field"].
field is in the other entity (name of the variable in the class not the table in the database)..

If you don't do that, hibernate will map this two relation as it's not the same relation

so we need to tell hibernate to do the mapping in one side only and co-ordinate between them.

just take the string and use the JavaScriptSerializer to deserialize it into a native object. For example, having this json:

string json = "[{Name:'John Simith',Age:35},{Name:'Pablo Perez',Age:34}]"; 

You'd need to create a C# class called, for example, Person defined as so:

public class Person
{
 public int Age {get;set;}
 public string Name {get;set;}
}

You can now deserialize the JSON string into an array of Person by doing:

JavaScriptSerializer js = new JavaScriptSerializer();
Person [] persons =  js.Deserialize<Person[]>(json);

Here's a link to JavaScriptSerializer documentation.

Note: my code above was not tested but that's the idea Tested it. Unless you are doing something "exotic", you should be fine using the JavascriptSerializer.
